One-point­calibration­for­TDL­gas­sensors­
Enter calibration mode as described in section 7.1 "Enter Calibration Mode".
A one-point calibration of gas sensors is always a slope (i.e. with air) calibra-
tion. A one point slope calibration is done in air or any other calibration gas with
defined gas concentration.
Select 1 point as calibration type.
Press [ENTER].
Enter values for the effective temperature and pressure values of the gas used
for calibration. When using the calibration tube for calibration, use values mea-
sured manually for the gas present in the calibration tube.
Adjust the optical path length for your individual system.
Place the sensor in the calibration gas (e.g. air). Press [ENTER].
Depending on the used drift control (see chapter 8.2.3.5) one of the two follow-
ing modes is active.
Process­calibration­for­TDL­gas­sensors
Enter calibration mode as described in section 7.1 "Enter Calibration Mode".
A process calibration of gas sensors is always a slope calibration.
Select Process as the calibration type.
Press [ENTER]
Take a sample and press the [ENTER] key again to store the current measuring
value. To show the ongoing calibration process, A or B (depending on the chan-
nel) is blinking in the display.
After determining the concentration value of the sample press the
to proceed with the calibration.
