Hi

Lo

Hi

—

+

Do not apply any voltages to the output terminals except for the 20 mA SINK range. If

voltage is applied mistakenly, the internal circuit may be damaged.

As the instrument is calibrated without the voltage drop of the lead cables, error due to

the resistance of the lead cables (approx. 0.1 Ω for go and return) must be considered for

load current measurement.

5.2 Generating DC Current or DC Voltage

The instrument generates voltage or current at a specified value through the output terminals. In valid

ranges, terminal-to-terminal connection opens, and the display unit indicates «-nC-» and «OFF.»

ment of Keys for Calibration” section below) for about 2 seconds to enter the calibration
mode.

<5> Select the generation range to calibrate using the MEASURE/SOURCE selection switch

and range selection rotary switch. The display unit shows “CAL,” “SOURCE,” “ON,” “0,” and
the lower limit.

<6> Read the output value of the CA11E using the standard (digital multimeter), and using the

[▲] and [▼] adjustment keys adjust the CA11E so that the output value is set to the offset
value. Then press the [▼1] input determination (ENTER) key to fix the setting.
After fixing the setting, the display unit reading changes to “CAL,” “SOURCE,” “ON,” “FS,”
and a full scale of the range.

<7> Read the output value of the CA11E using the standard (digital multimeter), and using the

[▲] and [▼] adjustment keys adjust the CA11E so that the output value is set to the full
scale value. Then press and hold the [▼1] input determination (ENTER) key for about 1
second to fix the setting.
After fixing the setting, the display unit shows “0 FS” blinking. Re-press and hold the [▼1]
input determination (ENTER) key for about 1 second to write the calibration coefficients to
the EEPROM of the instrument. (This overwrites the previous calibration coefficients.)

Назначение

Калибраторы электрических сигналов СА11Е, СА12Е, СА51, СА71, СА150, СА450 (далее — калибраторы) предназначены для измерения и воспроизведения напряжения постоянного и переменного тока, силы постоянного тока, частоты переменного тока, электрического сопротивления постоянному току (в том числе от термопар и термопреобразователей сопротивления).

Описание

Калибраторы представляют собой портативные электрические приборы с расположенными на передней панели жидкокристаллическим дисплеем с регулируемой подсветкой и клавишами, которые группируются в соответствии с их функциями.

Калибраторы различных моделей отличаются функциональными возможностями, метрологическими и техническими характеристиками. Функциональные возможности калибраторов в зависимости от модели приведены в таблице 1.

Питание калибраторов осуществляется как от батарей, так и от сети переменного тока при использовании специального адаптера. Наличие во всех калибраторах, кроме СА12Е, встроенного источника питания постоянного тока 24 В позволяет использовать калибраторы в качестве источника питания для датчиков.

На рисунке 1 приведён общий вид калибраторов CA11E, CA12E, на рисунке 2 приведена схема пломбирования калибраторов CA11E, CA12E.
