• General information2.1.3 Class 1 Laser

  A Class 1 LASER is installed in this instrument. Class 1 LASERS
  are products where the radiant power of the LASER beam accessible
  (the accessible emission) is always below the Maximum Permissible
  Exposure value. Therefore, for Class 1 LASERS the output power is
  below the level at which it is believed eye damage will occur.
  Exposure to the beam of a Class 1 LASER will not result in eye
  injury. Class 1 LASERS may therefore be considered safe. However,
  Class 1 LASER products may contain LASER systems of a higher Class
  but there are adequate engineering control measures to ensure that
  access to the beam is not reasonably likely. This Class 1 Laser
  product complies with 21 CFR Chapter 1, subchapter J. It is
  evaluated and tested in accordance with EN 61010-1, Safety
  Requirements for Electrical Equipment for Measurement and Control
  and Laboratory Use and IEC/EN 60825-1, Safety of Laser
  Products.

• General informationThe particle counters use a laser-diode light
  source and collection optics for particle detection. Particles
  scatter light from the laser diode. The collection optics focus the
  light onto a photo diode that converts the bursts of light into
  electrical pulses. The pulse height is proportional to the particle
  size. Pulses are counted and their amplitude is measured for
  particle sizing. Results are shown as particle counts in the
  specified size range (differential count mode) or as total particle
  counts (cumulative count mode). A microprocessor controls all
  instrument functions. Count data is shown as cumulative counts or
  differential counts.

  The particle counter is thoroughly inspected and tested at the
  factory and is ready for use upon receipt. When received, inspect
  the shipping carton for damage. If the carton is damaged, notify
  the carrier and save the carton for carrier inspection. Inspect the
  counter for broken parts, scratches, dents or other damage.

  2.4 How to use the touchscreen interfaceThe MET ONE 3400 is
  operated by use of a TFT color touchscreen located on the front
  panel of the unit (Figure 3 on page 18). All commands are executed
  through the touchscreen.

  Make contact with the screen through the use of a single finger
  or the provided stylus.

  Notice: To avoid damage to the touchscreen interface, only make
  contact with a finger or the provided stylus. Avoid the use of
  sharp objects or the writing end of pens and pencils. Use only
  light touchnever use force with the touchscreen interface.

  2.4.1 Touchscreen interaction terminologyThroughout this
  document, user interaction with the touchscreen will be described
  with specific terminology (Table 2).

  Screen items commonly referred to in this manual include:

  A screen is a window of the Graphical User Interface (GUI) which
  takes up all visible space on the touchscreen and can only be
  exited by pressing a button.

  A tab is a subdivision of the GUI easily accessed by touching
  the tab at the top of the screen.

  An icon is an area of the touchscreen that should be touched to
  access another screen or execute an action (such as performing a
  sample run).

• Installation3.2 Electrical installation

  3.2.1 Wiring safety informationFollow all warnings and notes
  when making wiring connections to the instrument (Safety
  information on page 9).

  DANGERElectric shock hazard. Always disconnect power to the
  instrument when making electrical connections.

  3.2.1.1 Electrostatic discharge (ESD) considerations Important
  Note: To minimize hazards and ESD risks, maintenance procedures not
  requiring power to the counter should be performed with power
  removed.

  Delicate internal electronic components can be damaged by static
  electricity, resulting in degraded instrument performance or
  eventual failure.

  The manufacturer recommends taking the following steps to
  prevent ESD damage to your instrument:

  Before touching any instrument electronic components (such as
  printed circuit cards and the components on them) discharge static
  electricity from the body. To discharge static electricity, touch
  an earth-grounded metal surface such as the chassis of an
  instrument, or a metal conduit or pipe.

  To reduce static build-up, avoid excessive movement. Transport
  static-sensitive components in anti-static containers or
  packaging.

  To discharge static electricity from the body and keep it
  discharged, wear a wrist strap connected by a wire to earth
  ground.

  Handle all static-sensitive components in a static-safe area. If
  possible, use anti-static floor pads and work bench pads. 16

  5.3 Area management

  Locations, Areas and GroupsThe sampling positions (or LOCATIONS)
  can be organized within larger spaces (or AREAS). This arrangement
  is a function of the geographical placement of the sampling
  position within a facility. Data from each sampling position (or
  LOCATION) is associated with a unique numerical designation
  assigned automatically by the instrument (range of 001 to 999) plus
  the common name for that point assigned by the user, such as LAF
  Bench 32 or Diffusion Oven Loader. It is permissible to have
  duplicate LOCATION names within separate AREAS. For example, LAF
  Bench #2 could be a designation for Cleanroom 422 and also
  Cleanroom 423 as long as the combination of AREA/LOCATION name is
  unique.

  In addition, each sample point or LOCATION can be associated
  with a GROUP that has common sampling attributes or sampling recipe
  as defined by the user. Examples might be All ISO Class 7 positions
  in Building 4 or All Locations Sampled Once a Month. It is
  permissible for a LOCATION to belong to one or more GROUPS. It is
  also possible to have LOCATIONS that have no GROUP association at
  all.

  These combinations of LOCATIONS as AREAS or GROUPS allow for
  quicker development of sampling strategies relating to alarm
  levels, sampling methodology and/or frequency.

  Figure 15 Copy system configuration37

• ConfigurationOnce a library of LOCATIONS, AREAS and GROUPS is
  developed for a facility, this information can be rapidly
  transferred to other 3400 series instruments. To transfer the
  information, copy the configuration of the Master 3400 to a USB
  memory stick and then transfer that configuration to the remaining
  3400 particle counters. Refer to Copy a configuration to USB drive
  (memory stick) on page 36.

  6. Push RETURN to return to the Group Settings screen.

  It is possible to set a particle count alarm based either on a
  direct or raw count value reaching a limit, or on a concentration
  or calculated alarm limit. The raw count alarm is triggered
  whenever one or more of the limits set for the active size channels
  have been reached during a count cycle. The concentration alarm
  limits can be used to establish alarm limits based on a calculated
  volume such as a cubic foot or a cubic meter, even if the total
  volume of air sampled during a count cycle does not equal the
  specified volume.

  As an example, to set the 0.5 m alarm limits for an ISO Class 5
  area based on a calculated volume, the concentration mode would be
  set to counts per cubic meter and the alarm limit set to 3520.
  During the ensuing count cycle(s), the instrument assesses the
  potential alarm condition based on the volume of air sampled up to
  that moment and the volume of air for which the limit is set. The
  alarm is triggered whenever the calculated value (based on actual
  counts, the actual sampled volume, and the target total volume)
  reaches the value set by the user in the concentration alarm
  column.

  5.6 Sizes Feature (Optional)The Sizes icon does not appear
  unless the option is purchased separately. The instrument must be
  calibrated by the manufacturer before the Sizes feature can be
  enabled.

  5.6.1 Size ConfigurationImportant Note: Changes made in Size
  Setup cause all stored count data to be deleted. The first channel
  must remain fixed at 0.3 or 0.5 m for proper operation and must not
  be changed.

  The MET ONE 3400 can have up to 8 sizes loaded at a time with
  the optional 8-channel selectable size option (P/N 2088439). When
  the 8-channel option is selected, the MET ONE 3400 will be
  calibrated for the following sized particles:

  0.3 to 10-m range: 0.3, 0.4, 0.5, 0.7, 0.8, 1.0, 2.0, 3.0, 4.0,
  5.0, 7.0 and 10.0.

  0.5 to 25-m range: 0.5, 0.6, 0.7, 0.8, 1.0, 2.0, 3.0, 5.0, 7.0,
  10.0, 15.0 and 25.0.

  With the 8-channel selectable option turned on, any size within
  the range loaded (in increments of 0.1 m only) can be selected. If
  a channel is selected (out of the selectable 8 channel option) that
  was not calibrated, the counting is based on interpolations.

  There can be an appreciable margin of error when measuring an
  interpolated size for which the channel is not calibrated with a
  calibration particle. A maximum of 15% size

• General information2.1.3 Class 1 Laser

  A Class 1 LASER is installed in this instrument. Class 1 LASERS
  are products where the radiant power of the LASER beam accessible
  (the accessible emission) is always below the Maximum Permissible
  Exposure value. Therefore, for Class 1 LASERS the output power is
  below the level at which it is believed eye damage will occur.
  Exposure to the beam of a Class 1 LASER will not result in eye
  injury. Class 1 LASERS may therefore be considered safe. However,
  Class 1 LASER products may contain LASER systems of a higher Class
  but there are adequate engineering control measures to ensure that
  access to the beam is not reasonably likely. This Class 1 Laser
  product complies with 21 CFR Chapter 1, subchapter J. It is
  evaluated and tested in accordance with EN 61010-1, Safety
  Requirements for Electrical Equipment for Measurement and Control
  and Laboratory Use and IEC/EN 60825-1, Safety of Laser
  Products.

  This symbol identifies the location of a fuse or current
  limiting device.

  This symbol indicates that the instrument contains a Class 1
  LASER device.LASER CLASS 110

• General informationThe particle counters use a laser-diode light
  source and collection optics for particle detection. Particles
  scatter light from the laser diode. The collection optics focus the
  light onto a photo diode that converts the bursts of light into
  electrical pulses. The pulse height is proportional to the particle
  size. Pulses are counted and their amplitude is measured for
  particle sizing. Results are shown as particle counts in the
  specified size range (differential count mode) or as total particle
  counts (cumulative count mode). A microprocessor controls all
  instrument functions. Count data is shown as cumulative counts or
  differential counts.

  The particle counter is thoroughly inspected and tested at the
  factory and is ready for use upon receipt. When received, inspect
  the shipping carton for damage. If the carton is damaged, notify
  the carrier and save the carton for carrier inspection. Inspect the
  counter for broken parts, scratches, dents or other damage.

  2.4 How to use the touchscreen interfaceThe MET ONE 3400 is
  operated by use of a TFT color touchscreen located on the front
  panel of the unit (Figure 3 on page 18). All commands are executed
  through the touchscreen.

  Make contact with the screen through the use of a single finger
  or the provided stylus.

  Notice: To avoid damage to the touchscreen interface, only make
  contact with a finger or the provided stylus. Avoid the use of
  sharp objects or the writing end of pens and pencils. Use only
  light touchnever use force with the touchscreen interface.

  2.4.1 Touchscreen interaction terminologyThroughout this
  document, user interaction with the touchscreen will be described
  with specific terminology (Table 2).

  Screen items commonly referred to in this manual include:

  A screen is a window of the Graphical User Interface (GUI) which
  takes up all visible space on the touchscreen and can only be
  exited by pressing a button.

  A tab is a subdivision of the GUI easily accessed by touching
  the tab at the top of the screen.

  An icon is an area of the touchscreen that should be touched to
  access another screen or execute an action (such as performing a
  sample run).

  3.2.1 Wiring safety informationFollow all warnings and notes
  when making wiring connections to the instrument (Safety
  information on page 9).

  DANGERElectric shock hazard. Always disconnect power to the
  instrument when making electrical connections.

  3.2.1.1 Electrostatic discharge (ESD) considerations Important
  Note: To minimize hazards and ESD risks, maintenance procedures not
  requiring power to the counter should be performed with power
  removed.

  Delicate internal electronic components can be damaged by static
  electricity, resulting in degraded instrument performance or
  eventual failure.

  The manufacturer recommends taking the following steps to
  prevent ESD damage to your instrument:

  Before touching any instrument electronic components (such as
  printed circuit cards and the components on them) discharge static
  electricity from the body. To discharge static electricity, touch
  an earth-grounded metal surface such as the chassis of an
  instrument, or a metal conduit or pipe.

  To reduce static build-up, avoid excessive movement. Transport
  static-sensitive components in anti-static containers or
  packaging.

  To discharge static electricity from the body and keep it
  discharged, wear a wrist strap connected by a wire to earth
  ground.

  Handle all static-sensitive components in a static-safe area. If
  possible, use anti-static floor pads and work bench pads. 16

• Installation3.2.2 Electrical connectionsConnect probes, external
  power, cables or USB devices to the Model 3400 to expand counter
  functionality or download data. Make connections where indicated
  (Figure 2 and Figure 3 on page 18).

  Batteries installed in the particle counter will charge when the
  AC power cord is connected. An external battery charger is also
  available for maximum efficiency (Section 11 on page 99). Contact a
  local Hach Company agent at 800.866.7889 or +1.541.472.6500 to
  order.

  Batteries charged in the 3400 will take approximately 10 hours
  to charge completely.

  Batteries charged in an external charger will take approximately
  7 hours to charge completely.

  Depending on the hysteresis characteristics and calibration
  status of the battery system, batteries may not be 100% chargeable
  during each charge cycle. Batteries are considered fully charged if
  the display reads between 95% and 100%.

  Note: It is recommended that a battery is recalibrated using the
  smart battery charger (280-300-5000) if a fully charged battery
  shows less than 95% charge.

  The battery status for batteries installed in the counter is
  indicated by the state of the LED on the front of the unit (Table
  4).

  5.3 Area management

  Locations, Areas and GroupsThe sampling positions (or LOCATIONS)
  can be organized within larger spaces (or AREAS). This arrangement
  is a function of the geographical placement of the sampling
  position within a facility. Data from each sampling position (or
  LOCATION) is associated with a unique numerical designation
  assigned automatically by the instrument (range of 001 to 999) plus
  the common name for that point assigned by the user, such as LAF
  Bench 32 or Diffusion Oven Loader. It is permissible to have
  duplicate LOCATION names within separate AREAS. For example, LAF
  Bench #2 could be a designation for Cleanroom 422 and also
  Cleanroom 423 as long as the combination of AREA/LOCATION name is
  unique.

  In addition, each sample point or LOCATION can be associated
  with a GROUP that has common sampling attributes or sampling recipe
  as defined by the user. Examples might be All ISO Class 7 positions
  in Building 4 or All Locations Sampled Once a Month. It is
  permissible for a LOCATION to belong to one or more GROUPS. It is
  also possible to have LOCATIONS that have no GROUP association at
  all.

  These combinations of LOCATIONS as AREAS or GROUPS allow for
  quicker development of sampling strategies relating to alarm
  levels, sampling methodology and/or frequency.

  Figure 15 Copy system configuration37

• ConfigurationOnce a library of LOCATIONS, AREAS and GROUPS is
  developed for a facility, this information can be rapidly
  transferred to other 3400 series instruments. To transfer the
  information, copy the configuration of the Master 3400 to a USB
  memory stick and then transfer that configuration to the remaining
  3400 particle counters. Refer to Copy a configuration to USB drive
  (memory stick) on page 36.

  5.5 Group managementA group is a series of locations that have
  common sampling parameters or recipe (Figure 21 on page 44). The
  locations in a group do not need to be geographically co-located.
  When a group is loaded for sampling, the operator only sees the
  locations that are added to the active group on the sample screen.
  Upon completion of sampling in one location, the operator must
  press the +/- button on the sample screen to advance to the next
  sampling location in the active group. The order of this
  progression is set in the Group Settings screen by setting the
  order of the list of sample point locations within the Locations
  window. Refer to section 5.5.6 on page 45.

  6. Push RETURN to return to the Group Settings screen.

  It is possible to set a particle count alarm based either on a
  direct or raw count value reaching a limit, or on a concentration
  or calculated alarm limit. The raw count alarm is triggered
  whenever one or more of the limits set for the active size channels
  have been reached during a count cycle. The concentration alarm
  limits can be used to establish alarm limits based on a calculated
  volume such as a cubic foot or a cubic meter, even if the total
  volume of air sampled during a count cycle does not equal the
  specified volume.

  As an example, to set the 0.5 m alarm limits for an ISO Class 5
  area based on a calculated volume, the concentration mode would be
  set to counts per cubic meter and the alarm limit set to 3520.
  During the ensuing count cycle(s), the instrument assesses the
  potential alarm condition based on the volume of air sampled up to
  that moment and the volume of air for which the limit is set. The
  alarm is triggered whenever the calculated value (based on actual
  counts, the actual sampled volume, and the target total volume)
  reaches the value set by the user in the concentration alarm
  column.

  5.6 Sizes Feature (Optional)The Sizes icon does not appear
  unless the option is purchased separately. The instrument must be
  calibrated by the manufacturer before the Sizes feature can be
  enabled.

  5.6.1 Size ConfigurationImportant Note: Changes made in Size
  Setup cause all stored count data to be deleted. The first channel
  must remain fixed at 0.3 or 0.5 m for proper operation and must not
  be changed.

  The MET ONE 3400 can have up to 8 sizes loaded at a time with
  the optional 8-channel selectable size option (P/N 2088439). When
  the 8-channel option is selected, the MET ONE 3400 will be
  calibrated for the following sized particles:

  0.3 to 10-m range: 0.3, 0.4, 0.5, 0.7, 0.8, 1.0, 2.0, 3.0, 4.0,
  5.0, 7.0 and 10.0.

  0.5 to 25-m range: 0.5, 0.6, 0.7, 0.8, 1.0, 2.0, 3.0, 5.0, 7.0,
  10.0, 15.0 and 25.0.

  With the 8-channel selectable option turned on, any size within
  the range loaded (in increments of 0.1 m only) can be selected. If
  a channel is selected (out of the selectable 8 channel option) that
  was not calibrated, the counting is based on interpolations.

  There can be an appreciable margin of error when measuring an
  interpolated size for which the channel is not calibrated with a
  calibration particle. A maximum of 15% size

• General information2.1.3 Class 1 Laser

  A Class 1 LASER is installed in this instrument. Class 1 LASERS
  are products where the radiant power of the LASER beam accessible
  (the accessible emission) is always below the Maximum Permissible
  Exposure value. Therefore, for Class 1 LASERS the output power is
  below the level at which it is believed eye damage will occur.
  Exposure to the beam of a Class 1 LASER will not result in eye
  injury. Class 1 LASERS may therefore be considered safe. However,
  Class 1 LASER products may contain LASER systems of a higher Class
  but there are adequate engineering control measures to ensure that
  access to the beam is not reasonably likely. This Class 1 Laser
  product complies with 21 CFR Chapter 1, subchapter J. It is
  evaluated and tested in accordance with EN 61010-1, Safety
  Requirements for Electrical Equipment for Measurement and Control
  and Laboratory Use and IEC/EN 60825-1, Safety of Laser
  Products.

• General informationThe particle counters use a laser-diode light
  source and collection optics for particle detection. Particles
  scatter light from the laser diode. The collection optics focus the
  light onto a photo diode that converts the bursts of light into
  electrical pulses. The pulse height is proportional to the particle
  size. Pulses are counted and their amplitude is measured for
  particle sizing. Results are shown as particle counts in the
  specified size range (differential count mode) or as total particle
  counts (cumulative count mode). A microprocessor controls all
  instrument functions. Count data is shown as cumulative counts or
  differential counts.

  The particle counter is thoroughly inspected and tested at the
  factory and is ready for use upon receipt. When received, inspect
  the shipping carton for damage. If the carton is damaged, notify
  the carrier and save the carton for carrier inspection. Inspect the
  counter for broken parts, scratches, dents or other damage.

  2.4 How to use the touchscreen interfaceThe MET ONE 3400 is
  operated by use of a TFT color touchscreen located on the front
  panel of the unit (Figure 3 on page 18). All commands are executed
  through the touchscreen.

  Make contact with the screen through the use of a single finger
  or the provided stylus.

  Notice: To avoid damage to the touchscreen interface, only make
  contact with a finger or the provided stylus. Avoid the use of
  sharp objects or the writing end of pens and pencils. Use only
  light touchnever use force with the touchscreen interface.

  2.4.1 Touchscreen interaction terminologyThroughout this
  document, user interaction with the touchscreen will be described
  with specific terminology (Table 2).

  Screen items commonly referred to in this manual include:

  A screen is a window of the Graphical User Interface (GUI) which
  takes up all visible space on the touchscreen and can only be
  exited by pressing a button.

  A tab is a subdivision of the GUI easily accessed by touching
  the tab at the top of the screen.

  An icon is an area of the touchscreen that should be touched to
  access another screen or execute an action (such as performing a

• Installation3.2 Electrical installation

  3.2.1 Wiring safety informationFollow all warnings and notes
  when making wiring connections to the instrument (Safety
  information on page 9).

  DANGERElectric shock hazard. Always disconnect power to the
  instrument when making electrical connections.

  3.2.1.1 Electrostatic discharge (ESD) considerations Important
  Note: To minimize hazards and ESD risks, maintenance procedures not
  requiring power to the counter should be performed with power
  removed.

  Delicate internal electronic components can be damaged by static
  electricity, resulting in degraded instrument performance or
  eventual failure.

  The manufacturer recommends taking the following steps to
  prevent ESD damage to your instrument:

  Before touching any instrument electronic components (such as
  printed circuit cards and the components on them) discharge static
  electricity from the body. To discharge static electricity, touch
  an earth-grounded metal surface such as the chassis of an
  instrument, or a metal conduit or pipe.

  To reduce static build-up, avoid excessive movement. Transport
  static-sensitive components in anti-static containers or
  packaging.

  To discharge static electricity from the body and keep it
  discharged, wear a wrist strap connected by a wire to earth
  ground.

  Handle all static-sensitive components in a static-safe area. If
  possible, use anti-static floor pads and work bench pads. 16

• Installation3.2.2 Electrical connectionsConnect probes, external
  power, cables or USB devices to the Model 3400 to expand counter
  functionality or download data. Make connections where indicated

  5.3 Area management

  Locations, Areas and GroupsThe sampling positions (or LOCATIONS)
  can be organized within larger spaces (or AREAS). This arrangement
  is a function of the geographical placement of the sampling
  position within a facility. Data from each sampling position (or
  LOCATION) is associated with a unique numerical designation
  assigned automatically by the instrument (range of 001 to 999) plus
  the common name for that point assigned by the user, such as LAF
  Bench 32 or Diffusion Oven Loader. It is permissible to have
  duplicate LOCATION names within separate AREAS. For example, LAF
  Bench #2 could be a designation for Cleanroom 422 and also
  Cleanroom 423 as long as the combination of AREA/LOCATION name is
  unique.

  In addition, each sample point or LOCATION can be associated
  with a GROUP that has common sampling attributes or sampling recipe
  as defined by the user. Examples might be All ISO Class 7 positions
  in Building 4 or All Locations Sampled Once a Month. It is
  permissible for a LOCATION to belong to one or more GROUPS. It is
  also possible to have LOCATIONS that have no GROUP association at
  all.

  These combinations of LOCATIONS as AREAS or GROUPS allow for
  quicker development of sampling strategies relating to alarm
  levels, sampling methodology and/or frequency.

  Figure 15 Copy system configuration37

• ConfigurationOnce a library of LOCATIONS, AREAS and GROUPS is
  developed for a facility, this information can be rapidly
  transferred to other 3400 series instruments. To transfer the
  information, copy the configuration of the Master 3400 to a USB
  memory stick and then transfer that configuration to the remaining
  3400 particle counters. Refer to Copy a configuration to USB drive
  (memory stick) on page 36.

  6. Push RETURN to return to the Group Settings screen.

  It is possible to set a particle count alarm based either on a
  direct or raw count value reaching a limit, or on a concentration
  or calculated alarm limit. The raw count alarm is triggered
  whenever one or more of the limits set for the active size channels
  have been reached during a count cycle. The concentration alarm
  limits can be used to establish alarm limits based on a calculated
  volume such as a cubic foot or a cubic meter, even if the total
  volume of air sampled during a count cycle does not equal the
  specified volume.

  As an example, to set the 0.5 m alarm limits for an ISO Class 5
  area based on a calculated volume, the concentration mode would be
  set to counts per cubic meter and the alarm limit set to 3520.
  During the ensuing count cycle(s), the instrument assesses the
  potential alarm condition based on the volume of air sampled up to
  that moment and the volume of air for which the limit is set. The
  alarm is triggered whenever the calculated value (based on actual
  counts, the actual sampled volume, and the target total volume)
  reaches the value set by the user in the concentration alarm
  column.

  5.6 Sizes Feature (Optional)The Sizes icon does not appear
  unless the option is purchased separately. The instrument must be
  calibrated by the manufacturer before the Sizes feature can be
  enabled.

  5.6.1 Size ConfigurationImportant Note: Changes made in Size
  Setup cause all stored count data to be deleted. The first channel
  must remain fixed at 0.3 or 0.5 m for proper operation and must not
  be changed.

  The MET ONE 3400 can have up to 8 sizes loaded at a time with
  the optional 8-channel selectable size option (P/N 2088439). When
  the 8-channel option is selected, the MET ONE 3400 will be
  calibrated for the following sized particles:

  0.3 to 10-m range: 0.3, 0.4, 0.5, 0.7, 0.8, 1.0, 2.0, 3.0, 4.0,
  5.0, 7.0 and 10.0.

  0.5 to 25-m range: 0.5, 0.6, 0.7, 0.8, 1.0, 2.0, 3.0, 5.0, 7.0,
  10.0, 15.0 and 25.0.

  With the 8-channel selectable option turned on, any size within
  the range loaded (in increments of 0.1 m only) can be selected. If
  a channel is selected (out of the selectable 8 channel option) that
  was not calibrated, the counting is based on interpolations.

  There can be an appreciable margin of error when measuring an
  interpolated size for which the channel is not calibrated with a
  calibration particle. A maximum of 15% size

  password function allows a system administrator to prevent users
  from modifying the counter settings. Once the feature password is
  enabled, the counter allows two types of access levels:

  The Administrator logon has permissions to change all settings
  on the particle counter.
