1. Select Settings > Sensor > Auto calibration and
confirm.
2. Select Enable or Disable confirm with [OK].
14.2 Capture range
The capture range blanks out measurement fluctuations.
Measurement fluctuations are minor variations in measured
values (such as signal noise, variations in concentration).
Those variations do not change the transmitted or displayed
value. Measured values within this range will be displayed
with the capture value. Measured values outside the capture
range will be displayed with the actual measured value.
Capture value (offset)
The capture value is displayed continuously, as long as the
measured value ranges between the upper and lower capture
value limits.
Upper capture value limit
The upper capture value limit marks the upper limit of the
range in which the capture value is displayed.

14.3 Resetting sensor
This function resets the sensor to factory default settings.
1. Select Settings > Sensor > Init. channel and confirm.
2. Select Confirm and confirm with [OK].
14.4 Setting calibration interval
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.

14.5 Setting sensor lock

This point is only valid for Polytron
87x0 IR.
1. Select Settings >Sensor > Sensor lock and confirm.
2. Select On or Off.
On The instrument rejects any sensor whose
part number does not match the part num-
ber of the previously installed sensor.
Off The instrument accepts any suitable sen-
sor, uploading the default settings of this
sensor. However, this overwrites any cus-
tomized settings with the default settings of
the new sensor.
