10.2.3 Calibrate Procedure
1 Click the Calibration icon on the Operation Screen, or click Settings >>
Calibration >> Calibrate.
2 Keep the probe in the background air.
3 Click the Next button to start the calibration procedure.
4 Click the Start button or the Probe button.
5 Expose the Probe to the Calibration Leak or the Calibration Gas. Keep it in
exposed position while the Calibration in progress bar is moving.
6 Remove the Probe when the display shows Remove probe and gives a sound
signal.
7 Continue the calibration routine until you can save the calibration.
Notice Wait at least 30 seconds between each calibration.
If the calibration is not saved, the instrument will revert to the previous
value.
When changing setup or probe you will need to repeat the exposure 2-3
times to get Calibration OK.
When performing a calibration the instrument will indicate if the probe
sensor has lost it’s sensitivity and needs to be changed. For information
about changing the probe sensor, see Chapter 14.4 “Changing Probe
Sensor” on p. 61.
