6.4.4.1 Accumulation measurement
For the calibration of an accumulation measurement, you must enter the accumulation
volume, i.e. the volume of the measurement chamber minus the volume of the
calibration leak. If you do not know the accumulation volume, you can carry out a
volume test - see below.
Volume test
ü
The device must be ready to measure (READY).
1 Place the calibration leak in the measurement chamber and close the
measurement chamber.
2
Select “Settings > Measurement settings > Accumulation volume/Volume test”.
3
A window opens in which you can set the calibration leak rate.
4
Confirm with “OK”.
The device measures and the calculated volume is displayed. You can accept the
value by pressing “OK”.
Calibration sequence • In the main menu, select “Settings > Measurement settings > Accumulation
volume” and enter the net volume of the measurement chamber (volume of the
measurement chamber minus the volume of the calibration leak).
• In the main menu, select “Trigger > Trigger level 1” and enter the trigger level for
the upcoming measurement run, see Settings for the measurements [ } 51].
• In the main menu, select “Calibration > Test leak rate” and enter the leak rate of
the calibration leak.
• Place the calibration leak in the measurement chamber and close the
measurement chamber.
• Select “Start calibration”.
The device measures and the new calibration value is displayed. You can accept the
new calibration factor by pressing “OK”, or cancel it by selecting “Cancel”.
Ideally, the calibration factor is 1. If the calibration factor is less than 0.5 or greater
than 2, you can accept it but a warning message appears, stating that it is possible to
improve your measurement setup.
