10.3 How to Calibrate
10.3.1 Preparation
Calibration Gas
Is a high perception gas mix of well known content of Hydrogen in air, normally 10 ppm
Hydrogen in air.
1 Adapt a Probe tip Nozzle to the regulator on the gas bottle.
2 Open the regulator carefully so that very little gas is flowing out from the nozzle.
3 Close the regulator after use.
Calibration Leak
1 Fill the gas container to the indicated pressure.
2 Purge the hose from air via the Purge Valve on the leak.
Cal. Leak in Test Cycle Select the box if the calibration leak is integrated in
a test object or in the chamber wall.
A complete test cycle will be performed during
calibration (Active Probes only).
Cal. Leak Pressure This option is only visible if Leak in Test Cycle is
selected.
Makes it possible to adjust the pressure for the
Leak, so that it complies with the Leak's feeding
pressure that is specified in the certificate.
Set Cal. Leak Pressure This option is only visible if Leak in Test Cycle is
selected.
Indicates feeding pressure on Leak.
Prevent Start Test cycle can not be started if calibration is not
valid.
Automatic
(Active Probe only) This option is only visible if Leak in Test Cycle is
deselected.
The Active Probe will be automatically calibrated at
set interval.
Max Attempts This option is only visible if an Active Probe is
connected, Automatic Calibration selected and
Leak in Test Cycle deselected.
Set maximum numbers of recalibration attempts if
calibration fails. System will stop trying after this
number of attempts and instead display the manual
calibration button.
Notice Uncertain about the optimal calibration level for your application? Please
contact your local provider of the Leak Detector.
Notice Do not open the fill valve. Use the purge valve on the leak to release any
air trapped inside the leak housing.
