Карпрофен для кошек инструкция по применению

Carprofen Description

Carprofen is a non-steroidal anti-inflammatory drug (NSAID) of the propionic acid class that includes ibuprofen, naproxen, and ketoprofen. Carprofen is the nonproprietary designation for a substituted carbazole, 6-chloro-∝-methyl-9H-carbazole-2-acetic acid. The empirical formula is C15H12ClNO2 and the molecular weight 273.72. The chemical structure of carprofen is:

Carprofen is a white, crystalline compound. It is freely soluble in ethanol, but practically insoluble in water at 25°C.

Carprofen — Clinical Pharmacology

Carprofen is a non-narcotic, non-steroidal anti-inflammatory agent with characteristic analgesic and antipyretic activity approximately equipotent to indomethacin in animal models.1

The mechanism of action of carprofen, like that of other NSAlDs, is believed to be associated with the inhibition of cyclooxygenase activity. Two unique cyclooxygenases have been described in mammals.2 The constitutive cyclooxygenase, COX-1, synthesizes prostaglandins necessary for normal gastrointestinal and renal function. The inducible cyclooxygenase, COX-2, generates prostaglandins involved in inflammation. Inhibition of COX-l is thought to be associated with gastrointestinal and renal toxicity while inhibition of COX-2 provides anti-inflammatory activity. The specificity of a particular NSAID for COX-2 versus COX-1 may vary from species to species.3 In an in vitro study using canine cell cultures, carprofen demonstrated selective inhibition of COX-2 versus COX-1.4 Clinical relevance of these data has not been shown. Carprofen has also been shown to inhibit the release of several prostaglandins in two inflammatory cell systems: rat polymorphonuclear leukocytes (PMN) and human rheumatoid synovial cells, indicating inhibition of acute (PMN system) and chronic (synovial cell system) inflammatory reactions.1

Several studies have demonstrated that carprofen has modulatory effects on both humoral and cellular immune responses.5-9 Data also indicate that carprofen inhibits the production of osteoclast-activating factor (OAF), PGE1, and PGE2 by its inhibitory effects on prostaglandin biosynthesis.1

Based upon comparison with data obtained from intravenous administration, carprofen is rapidly and nearly completely absorbed (more than 90% bioavailable) when administered orally.l0 Peak blood plasma concentrations are achieved in 1-3 hours after oral administration of 1, 5, and 25 mg/kg to dogs. The mean terminal half-life of carprofen is approximately 8 hours (range 4.5-9.8 hours) after single oral doses varying from 1-35 mg/kg of body weight. After a 100 mg single intravenous bolus dose, the mean elimination half-life was approximately 11.7 hours in the dog. Carprofen is more than 99% bound to plasma protein and exhibits a very small volume of distribution.

Carprofen is eliminated in the dog primarily by biotransformation in the liver followed by rapid excretion of the resulting metabolites (the ester glucuronide of carprofen and the ether glucuronides of 2 phenolic metabolites, 7-hydroxy-carprofen and 8-hydroxy carprofen) in the feces (70-80%) and urine (10-20%). Some enterohepatic circulation of the drug is observed.

INDICATIONS:

Carprofen is indicated for the relief of pain and inflammation associated with osteoarthritis and for the control of postoperative pain associated with soft tissue and orthopedic surgeries in dogs.

Contraindications

Carprofen should not be used in dogs exhibiting previous hypersensitivity to carprofen.

Precautions

As a class, cyclooxygenase inhibitory NSAIDs may be associated with gastrointestinal, renal and hepatic toxicity. Effects may result from decreased prostaglandin production and inhibition of the enzyme cyclooxygenase which is responsible for the formation of prostaglandins from arachidonic acid.11-14 When NSAlDs inhibit prostaglandins that cause inflammation they may also inhibit those prostaglandins which maintain normal homeostatic function. These anti-prostaglandin effects may result in clinically significant disease in patients with underlying or pre-existing disease more often than in healthy patients.12,14 NSAID therapy could unmask occult disease which has previously been undiagnosed due to the absence of apparent clinical signs. Patients with underlying renal disease for example, may experience exacerbation or decompensation of their renal disease while on NSAID therapy.11-14 The use of parenteral fluids during surgery should be considered to reduce the potential risk of renal complications when using NSAlDs perioperatively.

Carprofen is an NSAID, and as with others in that class, adverse reactions may occur with its use. The most frequently reported effects have been gastrointestinal signs. Events involving suspected renal, hematologic, neurologic, dermatologic, and hepatic effects have also been reported. Patients at greatest risk for renal toxicity are those that are dehydrated, on concomitant diuretic therapy, or those with renal, cardiovascular, and/or hepatic dysfunction. Concurrent administration of potentially nephrotoxic drugs should be approached cautiously, with appropriate monitoring. Since NSAIDs possess the potential to induce gastrointestinal ulcerations and/or gastrointestinal perforations, concomitant use of carprofen and other anti-inflammatory drugs, such as NSAIDs or corticosteroids, should be avoided. If additional pain medication is needed after administration of the total daily dose of carprofen, a non-NSAID or non-corticosteroid class of analgesia should be considered. The use of another NSAID is not recommended. Sensitivity to drug-associated adverse reactions varies with the individual patient. Dogs that have experienced adverse reactions from one NSAID may experience adverse reactions from another NSAID. Carprofen treatment was not associated with renal toxicity or gastrointestinal ulceration in well-controlled safety studies of up to ten times the dose in dogs. Carprofen Caplets is not recommended for use in dogs with bleeding disorders (e.g., Von Willebrand’s disease), as safety has not been established in dogs with these disorders. The safe use of Carprofen Caplets in animals less than 6 weeks of age, pregnant dogs, dogs used for breeding purposes, or in lactating bitches has not been established. Studies to determine the activity of carprofen when administered concomitantly with other protein-bound or similarly metabolized drugs have not been conducted.

Drug compatibility should be monitored closely in patients requiring additional therapy. Such drugs commonly used include cardiac, anticonvulsant and behavioral medications. It has been suggested that treatment with carprofen may reduce the level of inhalant anesthetics needed.15

If additional pain medication is warranted after administration of the total daily dose of Carprofen Caplets, alternative analgesia should be considered. The use of another NSAID is not recommended. Consider appropriate washout times when switching from one NSAID to another or when switching from corticosteroid use to NSAID use.

Warnings

Keep out of reach of children. Not for human use. Consult a physician in cases of accidental ingestion by humans. For use in dogs only. Do not use in cats.

All dogs should undergo a thorough history and physical examination before initiation of NSAID therapy. Appropriate laboratory tests to establish hematological and serum biochemical baseline data prior to, and periodically during, administration of any NSAID should be considered. Owners should be advised to observe for signs of potential drug toxicity (see Information for Dog Owners, Adverse Reactions, Animal Safety and Post-Approval Experience).

INFORMATION FOR DOG OWNERS:

Carprofen Caplets, like other drugs of its class, is not free from adverse reactions. Owners should be advised of the potential for adverse reactions and be informed of the clinical signs associated with drug intolerance. Adverse reactions may include decreased appetite, vomiting, diarrhea, dark or tarry stools, increased water consumption, increased urination, pale gums due to anemia, yellowing of gums, skin or white of the eye due to jaundice, lethargy, incoordination, seizure, or behavioral changes.

Serious adverse reactions associated with this drug class can occur without warning and in rare situations result in death (see Adverse Reactions). Owners should be advised to discontinue Carprofen Caplets therapy and contact their veterinarian immediately if signs of intolerance are observed.

The vast majority of patients with drug related adverse reactions have recovered when the signs are recognized, the drug is withdrawn and veterinary care, if appropriate, is initiated. Owners should be advised of the importance of periodic follow up for all dogs during administration of any NSAID.

Adverse Reactions/Side Effects

During investigational studies of osteoarthritis with twice daily administration of 1 mg/lb, no clinically significant adverse reactions were reported. Some clinical signs were observed during field studies (n=297) which were similar for carprofen caplet- and placebo-treated dogs. Incidences of the following were observed in both groups: vomiting (4%), diarrhea (4%), changes in appetite (3%), lethargy (1.4%), behavioral changes (1 %), and constipation (0.3%). The product vehicle served as control.

There were no serious adverse events reported during clinical field studies with once daily oral administration of 2 mg/lb. The following categories of abnormal health observations were reported. The product vehicle served as control.

Clinical pathology parameters listed represent reports of increases from pre-treatment values; medical judgment is necessary to determine clinical relevance.

During investigational studies of surgical pain for the caplet formulation, no clinically significant adverse reactions were reported. The product vehicle served as control.

Carprofen Dosage and Administration

Always provide Client Information Sheet with prescription. Carefully consider the potential benefits and risk of Carprofen and other treatment options before deciding to use Carprofen. Use the lowest effective dose for the shortest duration consistent with individual response. The recommended dosage for oral administration to dogs is 2 mg/lb (4.4 mg/kg) of body weight daily. The total daily dose may be administered as 2 mg/lb of body weight once daily or divided and administered as 1 mg/lb (2.2 mg/kg) twice daily. For the control of postoperative pain, administer approximately 2 hours before the procedure. Caplets are scored and dosage should be calculated in half-caplet increments.

EFFECTIVENESS:

Confirmation of the effectiveness of carprofen for the relief of pain and inflammation associated with osteoarthritis and for the control of postoperative pain associated with soft tissue and orthopedic surgeries, was demonstrated in 5 placebo-controlled, masked studies examining the anti-inflammatory and analgesic effectiveness of carprofen in various breeds of dogs.

Separate placebo-controlled, masked, multicenter field studies confirmed the anti-inflammatory and analgesic effectiveness of carprofen when dosed at 2 mg/lb once daily or when divided and administered at 1 mg/lb twice daily. In these two field studies, dogs diagnosed with osteoarthritis showed statistically significant overall improvement based on lameness evaluations by the veterinarian and owner observations when administered carprofen at labeled doses.

Separate placebo-controlled, masked, multicenter field studies confirmed the effectiveness of carprofen for the control of postoperative pain when, dosed at 2 mg/lb once daily in various breeds of dogs. In these studies, dogs presented for ovariohysterectomy, cruciate repair and aural surgeries were administered carprofen preoperatively and for a maximum of 3 days (soft tissue) or 4 days (orthopedic) postoperatively. In general, dogs administered carprofen showed statistically significant improvement in pain scores compared to controls.

ANIMAL SAFETY STUDIES:

Laboratory studies in unanesthetized dogs and clinical field studies have demonstrated that carprofen is well tolerated in dogs after oral administration.

In target animal safety studies, carprofen was administered orally to healthy Beagle dogs at 1, 3, and 5 mg/lb twice daily (1, 3 and 5 times the recommended total daily dose) for 42 consecutive days with no significant adverse reactions. Serum albumin for a single female dog receiving 5 mg/lb twice daily decreased to 2.1 g/dL after 2 weeks of treatment, returned to the pre-treatment value (2.6 g/dL) after 4 weeks of treatment, and was 2.3 g/dL at the final 6-week evaluation. Over the 6-week treatment period, black or bloody stools were observed in 1 dog (1 incident) treated with 1 mg/lb twice daily and in 1 dog (2 incidents) treated with 3 mg/lb twice daily. Redness of the colonic mucosa was observed in 1 male that received 3 mg/lb twice daily.

Two of 8 dogs receiving 10 mg/lb orally twice daily (10 times the recommended total daily dose) for 14 days exhibited hypoalbuminemia. The mean albumin level in the dogs receiving this dose was lower (2.38 g/dL) than each of 2 placebo control groups (2.88 and 2.93 g/dL, respectively). Three incidents of black or bloody stool were observed in 1 dog. Five of 8 dogs exhibited reddened areas of duodenal mucosa on gross pathologic examination. Histologic examination of these areas revealed no evidence of ulceration, but did show minimal congestion of the lamina propria in 2 of the 5 dogs.

In separate safety studies lasting 13 and 52 weeks, respectively, dogs were administered orally up to 11.4 mg/lb/day (5.7 times the recommended total daily dose of 2 mg/lb) of carprofen. In both studies, the drug was well tolerated clinically by all of the animals. No gross or histologic changes were seen in any of the treated animals. In both studies, dogs receiving the highest doses had average increases in serum L-alanine aminotransferase (ALT) of approximately 20 IU.

In the 52-week study, minor dermatologic changes occurred in dogs in each of the treatment groups but not in the control dogs. The changes were described as slight redness or rash and were diagnosed as non-specific dermatitis. The possibility exists that these mild lesions were treatment related, but no dose relationship was observed.

Clinical field studies were conducted with 549 dogs of different breeds at the recommended oral doses for 14 days (297 dogs were included in a study evaluating 1 mg/lb twice daily and 252 dogs were included in a separate study evaluating 2 mg/lb once daily). In both studies the drug was clinically well tolerated and the incidence of clinical adverse reactions for carprofen-treated animals was no higher than placebo-treated animals (placebo contained inactive ingredients found in carprofen caplets). For animals receiving 1 mg/lb twice daily, the mean post-treatment serum ALT values were 11 IU greater and 9 IU less than pre-treatment values for dogs receiving carprofen and placebo, respectively. Differences were not statistically significant. For animals receiving 2 mg/lb once daily, the mean post-treatment serum ALT values were 4.5 IU greater and 0.9 IU less than pre-treatment values for dogs receiving carprofen and placebo, respectively. In the latter study, 3 carprofen-treated dogs developed a 3-fold or greater increase in (ALT) and/or (AST) during the course of therapy. One placebo-treated dog had a greater than 2-fold increase in ALT. None of these animals showed clinical signs associated with the laboratory value changes. Changes in clinical laboratory values (hematology and clinical chemistry) were not considered clinically significant. The 1 mg/lb twice daily course of therapy was repeated as needed at 2-week intervals in 244 dogs, some for as long as 5 years.

Clinical field studies were conducted in 297 dogs of different breeds undergoing orthopedic or soft tissue surgery. Dogs were administered 2 mg/lb of carprofen caplets two hours prior to surgery then once daily, as needed for 2 days (soft tissue surgery) or 3 days (orthopedic surgery). Carprofen was well tolerated when used in conjunction with a variety of anesthetic-related drugs. The type and severity of abnormal health observations in carprofen- and placebo-treated animals were approximately equal and few in number (see Adverse Reactions). The most frequent abnormal health observation was vomiting and was observed at approximately the same frequency in carprofen- and placebo-treated animals. Changes in clinicopathologic indices of hematopoetic, renal, hepatic, and clotting function were not clinically significant. The mean post-treatment serum ALT values were 7.3 IU and 2.5 IU less than pre-treatment values for dogs receiving carprofen and placebo, respectively. The mean post-treatment AST values were 3.1 IU less for dogs receiving carprofen and 0.2 IU greater for dogs receiving placebo.

Storage and Handling

Store at controlled room temperature 15º-30ºC (59º — 86ºF).

How is Carprofen supplied

Dog Owner Information about CARPROFEN CAPLETS for Osteoarthritis and Post-Surgical Pain (”car-prô-fen”)

This summary contains important information about Carprofen Caplets. You should read this information before you start giving your dog Carprofen Caplets and review it each time the prescription is refilled. This sheet is provided only as a summary and does not take the place of instructions from your veterinarian. Talk to your veterinarian if you do not understand any of this information or if you want to know more about Carprofen Caplets.

What is Carprofen Caplets?

Carprofen Caplets is a nonsteroidal anti-inflammatory drug (NSAID) that is used to reduce pain and inflammation (soreness) due to osteoarthritis and pain following surgery in dogs. Carprofen Caplets is a prescription drug for dogs. It is available as a caplet and is given to dogs by mouth. Osteoarthritis (OA) is a painful condition caused by “wear and tear” of cartilage and other parts of the joints that may result in the following changes or signs in your dog:

• Limping or lameness
• Decreased activity or exercise (reluctance to stand, climb stairs, jump or run, or difficulty in performing these activities)
• Stiffness or decreased movement of joints

To control surgical pain (e.g. for surgeries such as spays, ear procedures or orthopedic repairs) your veterinarian may administer Carprofen Caplets before the procedure and recommend that your dog be treated for several days after going home.

What kind of results can I expect when my dog is on Carprofen Caplets?

While Carprofen Caplets is not a cure for osteoarthritis, it can relieve the pain and inflammation of OA and improve your dog’s mobility.

• Response varies from dog to dog but can be quite dramatic.
• In most dogs, improvement can be seen in a matter of days.
• If Carprofen Caplets is discontinued or not given as directed, your dog’s pain and inflammation may come back.

Who should not take Carprofen Caplets?

Your dog should not be given Carprofen Caplets if he/she:

• Has had an allergic reaction to carprofen, the active ingredient of Carprofen Caplets.
• Has had an allergic reaction to aspirin or other NSAIDs
  (for example deracoxib, etodalac, firocoxib, meloxicam, phenylbutazone or tepoxalin) such as hives, facial swelling, or red or itchy skin.

Carprofen Caplets should be given to dogs only. Cats should not be given Carprofen Caplets. Call your veterinarian immediately if your cat receives Carprofen Caplets. People should not take Carprofen Caplets. Keep Carprofen Caplets and all medicines out of reach of children. Call your physician immediately if you accidentally take Carprofen Caplets.

How to give Carprofen Caplets to your dog.

Carprofen Caplets should be given according to your veterinarian’s instructions. Your veterinarian will tell you what amount of Carprofen Caplets is right for your dog and for how long it should be given. Carprofen Caplets should be given by mouth and may be given with or without food.

What to tell/ask your veterinarian before giving Carprofen Caplets.

Talk to your veterinarian about:

• The signs of OA you have observed (for example limping, stiffness).
• The importance of weight control and exercise in the management of OA.
• What tests might be done before Carprofen Caplets is prescribed.
• How often your dog may need to be examined by your veterinarian.
• The risks and benefits of using Carprofen Caplets.

Tell your veterinarian if your dog has ever had the following medical problems:

• Experienced side effects from Carprofen Caplets or other NSAIDs, such as aspirin
• Digestive upset (vomiting and/or diarrhea)
• Liver disease
• Kidney disease
• A bleeding disorder (for example, Von Willebrand’s disease)

Tell your veterinarian about:

• Any other medical problems or allergies that your dog has now or has had.
• All medicines that you are giving your dog or plan to give your dog, including those you can get without a prescription.

Tell your veterinarian if your dog is:

• Pregnant, nursing or if you plan to breed your dog.

What are the possible side effects that may occur in my dog during Carprofen Caplets therapy?

Carprofen Caplets, like other drugs, may cause some side effects. Serious but rare side effects have been reported in dogs taking NSAIDs, including Carprofen Caplets. Serious side effects can occur with or without warning and in rare situations result in death.

The most common NSAID-related side effects generally involve the stomach (such as bleeding ulcers), and liver or kidney problems. Look for the following side effects that can indicate your dog may be having a problem with Carprofen Caplets or may have another medical problem:

• Decrease or increase in appetite
• Vomiting
• Change in bowel movements (such as diarrhea, or black, tarry or bloody stools)
• Change in behavior (such as decreased or increased activity level, incoordination, seizure or aggression)
• Yellowing of gums, skin, or whites of the eyes (jaundice)
• Change in drinking habits (frequency, amount consumed)
• Change in urination habits (frequency, color, or smell)
• Change in skin (redness, scabs, or scratching)

It is important to stop therapy and contact your veterinarian immediately if you think your dog has a medical problem or side effect from Carprofen Caplets therapy. If you have additional questions about possible side effects, talk to your veterinarian.

Can Carprofen Caplets be given with other medicines?

Carprofen Caplets should not be given with other NSAIDs (for example aspirin, deracoxib, etodalac, firocoxib, meloxicam, tepoxalin) or steroids (for example cortisone, dexamethasone, prednisone, triamcinolone). Tell your veterinarian about all medicines you have given your dog in the past, and any medicines that you are planning to give with Carprofen Caplets. This should include other medicines that you can get without a prescription. Your veterinarian may want to check that all of your dog’s medicines can be given together.

What do I do in case my dog eats more than the prescribed amount of Carprofen Caplets?

Contact your veterinarian immediately if your dog eats more than the prescribed amount of Carprofen Caplets.

What else should I know about Carprofen Caplets?

This sheet provides a summary of information about Carprofen Caplets. If you have any questions or concerns about Carprofen Caplets, or osteoarthritis, or postoperative pain, talk to your veterinarian.

As with all prescribed medicines, Carprofen Caplets should only be given to the dog for which it was prescribed.It should be given to your dog only for the condition for which it was prescribed.

It is important to periodically discuss your dog’s response to Carprofen Caplets at regular check ups. Your veterinarian will best determine if your dog is responding as expected and if your dog should continue receiving Carprofen Caplets.

Осциллограф с 112 можно использовать как в лаборатории, так и в цеху. С его помощью осуществляется проверка и ремонт контрольно-измерительной аппаратуры. Конструкция прибора позволяет проводить оперативную проверку неисправностей.

Осциллограф С1-112 — внешний вид, назначение прибора

Предназначение осциллографа-мультиметра С1-112 (рис.1) состоит в диагностике и замере импульсов при функционировании в режиме осциллографа или мультиметра. Осцилографический режим позволяет исследовать импульсы амплитудного диапазона в 5 мВ — 250 В и временного — от 120 нс до 0.5с при частоте до 10МГц. С помощью прибора удается распознавать данные напряжения постоянного тока от 1 мВ до 1000 В и активное сопротивление в амплитуде от 1 Ом до 2.5 МОм, при этом на экране ЭЛТ появляется цифровой отчет.

Технические характеристики

Осциллографа с1 112 ключевые характеристики, начиная с коэффициента отклонения и др., подобраны в соответствии со сферой применения этого высокоточного прибора.

• Параметры вертикального отклонения;

• Канал горизонтального отклонения

• Погрешности прибора: для коэффициентов отклонения и разверток составляют менее 5 %; замер напряжений <[l±0,1(Un/Ux)]%; замер сопротивлений <[2±0,1(Rп/Rx).
• Режим мультиметра

• Параметры дисплея

• Габариты: 110 x 190 x 250 мм, масса — 3,5 кг.
• Входное напряжение: максимум = 250B (переменная составляющая ≤ 30B)

ВАЖНО! Для модели с1 112 также характерны низкая погрешность и высокая чувствительность.

Инструкция по применению

Для того, чтобы провести измерительные работы, следуйте инструкции:

• Подключаем осциллограф в сеть.
• После этого, используя тумблер, помеченный нужной маркоровкой (сеть) включаем питание.
• Далее осциллограф необходимо прогреть. Это помогает стабилизировать все параметры, что важно для дальнейшей работы. Для прогревания устройства достаточно пяти минут.
• Используем регуляторы, промаркированные как «усиление Y» и «развертка», устанавливаем с их помощью измерительный луч, который появится по центру дисплея.

ВАЖНО! Такого вида калибровкой можно пользоваться лишь в случае, когда длительность находится в режиме одной миллисекунды.

• Перед измерением сигнала, проводимое путем регулирования положения рукояток (изменяем длительность и ускорение), поворачиваем их влево до конца.
• Благодаря усилению диапазон измерения изменяется до появления на экране максимально различимых сигналов. Частоту сигнала можно распознать по длительности.
• После установки регуляторов и получения стабильного сигнала на экране рассчитываем напряжение и частоту.

Осциллограф с1 112 а инструкция по применению идентична алгоритму использования версии с1 112.

Основные настройки

Осциллограф с1 112 имеет удобную и простую навигацию. Несмотря на высокую функциональность управлять прибором достаточно просто.

Для настройки прибора следует изучить кнопки, расположенные на нем:

• С помощью ручек «Фокус» и «Яркость» настраивается фикусировка луча, расположенного на экране, а также регулируется яркость. Для продления срока действия осциллографа рекомендуется выставлять минимальную яркость, но достаточную для четкой видимости показателей на экране.
• Настройка режима развертки «Ждущ-Авт». Кнопка позволяет выбрать ждущий или автоматический режим. В первом случае работа производится путем исследуемого сигнала. Автоматический режим запускает развертку без него. В большинстве случаев используют ждущий режим.
• Настройка синхронизации «Внутр-Внешн». Применение внешнего синхросигнала подразумевает применение отдельного источника сигнала. Поэтому в домашней мастерской чаще довольствуются внутренней синхронизацией.
• Выбор входа (открытый или закрытый ~ ). Открытый режим применяют в случае, когда необходимо исследовать сигнал с постоянной составляющей. В данном режиме сигнал, подающийся на вертикальное отклонение, содержит низкие частоты. Обычно применяется закрытый, так как при нем происходит отсечение (не появляется на экране) постоянной составляющей электрического сигнала.
• Кнопка с изображениями, напоминающими букву П, отвечает за полярность импульса запуска. С ее помощью выбирают положительную или отрицательную полярность.
• «Время/дел» — управление генератором развертки.
• Переключение входного делителя «V/дел». Если происходит исследование сигнала с неизвестной амплитудой, выставляем V/дел на максимум — 5. В данном положении одной клетке на сетке координат будет соответствовать напряжение в 5 вольт. При подключении к «Y» делителя, коэффициент деления которого равен 1 к 10, то значение клетки возрастет до 50 вольт.

ВАЖНО! С помощью клеммы «корпус» можно заземлить корпус аппарата. В случае, когда прибор не заземлен, мастера может ударить током, так как в режиме работы корпус часто находится под напряжением. Именно поэтому нельзя ставить осциллограф рядом с металлическими приборами, ведь дотронувшись до них одновременно человек получит электрический разряд. При работе не дотрагивайтесь до металлических частей прибора голыми руками.

Осциллограф с1 112а имеет идентичную систему калибровки.

Схема знакогенератора (рис.4) позволяет вырабатывать напряжение особенной формы, позволяющее получить одну матрицу на экране ЭЛТ и управлять напряжением.

Типичные поломки и ремонт устройства

При ремонте мультиметра следует учитывать, что этот элемент наполнен цифровыми микросхемами малой и средней степеней интеграции. Именно поэтому перед ремонтом следует проанализировать схему осциллографа с1 112 и временных диаграмм, чтобы до конца понять принципы функционирования прибора.

Диагностировать поломки проще всего путем проработки причин неисправностей во временных диаграммах сломанного прибора. Найти повреждения проще, пользуясь логическим анализатором, способным к одновременному исследованию сразу нескольких логических сигналов.

При неисправности цифровых узлов нужно обратить внимание на несколько положений:

1. Все логические микросхемы, выполняющие функцию И-НЕ, при поломке сохраняют на выходе микросхемы лог. «1» (если есть) на каждом из входов или лог. «0» (если есть) на каком-то из входов.
2. Неисправность логической микросхемы с функцией ИЛИ-НЕ часто диагностируют за счет сохранности на выходе лог. «1» (при ее присутствии на входах И) или сохранения на выходе лог. «0» (если присутствует там же на ИЛИ).
3. Указанные выше параметры действуют при исправности логических микросхем, загрузка которых осуществлена на неисправные. В такой ситуации возникает насильное подтягивание рабочих микросхем к 0 или подпитке нерабочих.
4. Чтобы проверить, действительно ли не работает микросхема, следует прервать контакт ее выхода со входами других.
5. Необходимо следить за амплитудой импульсов, не обозначенной на эпюрах напряжений, и ее соответствием уровням ТТЛ. Для лог. «1» амплитуда должна начинаться от 2,4 В, для лог. «0» — не подниматься выше 0,4 В.
6. Успешный ремонт осциллографа мультиметра с1 112а и его собрата с1 112 возможен только при условии владения информацией о режимах постоянного тока и временных диаграмм работы исправного аппарата (рис. 5).

Осциллограф С1-112 достаточно прост в эксплуатации, измерение напряжения проводит точно. Удобства прибора оценены в рамках использования в мастерских, а также учебных заведениях при проверке и ремонте электронной аппаратуры разных видов и назначения.

вскрыл свой С1-112А. Видно различия между С1-112, после доработки как и написано выше серию микросхем К155 частично поменяли на 555

частично заменили подстроечные резисторы

натыканные у 112го везде

на многооборотные

и СП3-16

злосчастный транзистор КТ816, в блоке питания ,стабилизатора линии +5в который перегревался от большой нагрузки от мультиметра ,стоя на плате даже без радиатора, тут вынесли на перегородку,

да еще и снизили потребляемый ток за счет 555 серии, теперь мультиметр вроде не должен доставлять проблем

Так же в С1-112А заменили полярные электролитические конденсаторы малой емкости (1 мкф) на неполярные слюдяные и пленочные

И всюду эти «красные флажки» и КТ325 в пластиковом корпусе

в блоке синхронизации и КВО

Достал платы мультиметра их две: плата АЦП и плата знакогенератора, тут даже «флажков» пожалели..

Решил перепаять для начала электролиты, их там не много 7 или 8 штук ,емкость (была 20мкф), стал выпаивать..»опа ! как легко отпаялся !»подумал я ,» а плата то двухсторонняя!»..а нее не отпаялся..колпачек снялся , а ножки с фольгой остались

, один выпаял более менее целым ..померял ESR метром

«живее всех живых!» аж 32 мкф..правда сопротивляется сильно, а так ничего вобщем поставил новые китайские с 5 кратным увеличением емоксти (другого нет в нашем колхозе) 100мкфх16в.

, покопался в закромах родины нашел «золотые запасы «(мечта КМщика!на аффинаж! ) зеленые «флажки» КМ-6 б/у емкостью 0,1мкФ и как учили (не все еще забыл) напаял прям поверх корпусов ,на мелкосхемы для блокировки по питанию, но т.к. запасы мои не велики, кое где пришлось по одному зеленому на 2 а то и 3 корпуса (но это все же лучше чем вообще ни чего) в плату знакогенератора

и плату АЦП

. Быстренько скидал все обратно (а по другому и не скажешь ведь! платы реально просто укладываются вдоль стенки и никак не крепятся! для одной есть пазы в пластике ,в низу, корпуса.а вторая вообще лежит между трубкой осциллографа и платой АЦП, а между ними прокладка из электрокартона и все! а, нет! еще сверху это дело прижимается планкой с парой пазов за счет винта.
включаю..и на экране в режиме вольтметра -0.000 как и должно быть! цифирки остановились и не бегают по кругу, только было собрался померять напряжение на батарейке..раз и один «сегмент» погас

. Разбирал уже три раза все промыл спиртом, проверил все пайки КМок поцарапал иголкой..похоже проблема в корпусе каком то..Будем разбираться..Почитал как это дело организовано, проблема вобщем в плате знакогенератора.
