5.2.2 Start Calibration

You can calibrate the T-Guard™ Leak Detection Sensor by selecting the following

submenu:

Main Menu

→

Calibration

→

Start Calibration.

After the calibration routine, you can accept the new calibration factor by pressing

OK or cancel the calibration by pressing Esc. A calibration factor of less than 0.2 or

more than 5 will result in a warning instead of a successful calibration. Refer to

Chapter 9for possible causes of errors and warnings.

The ideal calibration factor you can get is 1. If the calibration factor is smaller than

0.5 or greater than 2, you can confirm but you will receive a warning as hint that you

can improve your measuring arrangement.

Notice You have to recalibrate for every change of free volume in accumulation

mode and for every change of the carrier gas flow in Carrier Gas Mode.

This ensures a reliable measurement.
