1) Initial setting: see chapter “Tree diagram to the Settings menu”
2) Use the information indicated on the calibrated leak used for calibration or on its calibration certificate.
3) If sniffer test method selected
When the parameters are saved, all the data from all the set calibrated leaks (1 internal leak (
4
He) and
3 external leaks (
4
He, Mass 3 and H
2
)) is stored.
8.1.5 Target value
The target value is the value of the calibrated leak measured and corrected for temperature, taking into
account the loss/year.
The temperature and the loss/year must be taken into account on calculating the target value.
This information is provided on the calibrated leak identification label.
