5.10.6 Gas settings

This function sets the gas type, measuring range and units of
measurement.
Not all sensors offer a selection of values.
1. Select Settings > Sensor > Gas setting and confirm.
The current measured gas is displayed.
2. Select a measured gas from the list and confirm.
The current unit of measurement is displayed.
3. Select the unit of measurement from the list and confirm.
The current full scale deflection is displayed.
4. Set the full scale deflection and confirm (only for certain
sensors, see sensor data sheet).
The new full scale deflection is displayed.
5. Select Next and confirm.
An overview of the new gas settings is displayed.
6. After review: Select Back to menu for leaving the function
without changes and confirm with [OK].
7. Select Confirm to accept the settings and confirm with
[OK].
Information about units of measurement
Depending on the target gas, the units of measurement can be
switched between:
ppb

ppm

Vol%

%LEL

%LIE

%UEG

The instrument automatically converts the sensor signal into
the selected unit of measurement. Units which are not
available for a particular sensor or selected substance will not
be shown.
Information about the full scale deflection (measuring
range) and the analog output of 20 mA.
Some sensors offer a min/max range for the full scale
deflection.
The selected full scale deflection determines the output of the
20 mA signal on the analog interface.
Example:
Required range 0 to 500 ppm CO (e.g. part number 6809605
default 300 ppm, range min/max = 50/1000 ppm).
Select full scale deflection as 500 ppm. The analog output will
be linear between 4 mA = 0 ppm and 20 mA = 500 ppm.

5.10.7 Reset sensor

This function resets all sensor parameters to the factory default
settings see Section 7 on Page 36.
1. Select Settings > Sensor > Init. channel and confirm.
2. Select Confirm and confirm with [OK].

5.10.8 Calibration interval

NOTICE
i i
The calibration interval can be set between 0 and
720 days.
After the calibration interval expires, the instrument will issue a
warning that the calibration is past due.
1. Select Settings > Sensor > Cal. interval and confirm.
2. Set the calibration interval and confirm.

5.10.9 Set sensor test

This function is only active for Polytron 8100 using the EC
sensor.
This function is only active it the sensor test or diagnostics
dongle is installed.
This function periodically initiates the sensor self-test.
1. Select Settings > Sensor > Set sensor-test and confirm.
2. Select Enable or Disable and confirm.

5.10.10 Fast response

This function is only activated for Polytron 87x0 using the
PIR 7x00 sensor.

5.10.11 Display capture

1. Select Settings > Sensor > Display capture and confirm.
The offset can be set in the first window. This value is
output if the measurement value is inside the display
capture range. The lowest value of the capture range,
relative to the capture offset, can be set in the second
window. The highest value of the capture range, relative to
the capture offset, can be set in the third window. All values
are displayed in the 4th window. If one or several values
(capture offset, capture offset - capture low, capture offset
+ capture high) outside the allowed capture range, the
allowed capture range is displayed.
