The gas measurement to be calibrated is generally activated. If you want to calibrate a
deactivated measurement, activate the gas in the “Measuring parameters” menu.
After measuring and a short calculation period, the results of calibration are shown in
the display. The old and the new calibration factor as well as the old and the new
relative peak position are displayed.
1. Switch to measurement display.
2. Press the “Cal” button. The list of gases currently set for measurement is
displayed (up to four gases).
3. Select the gas that the measurement is to be calibrated for.
4. Check whether the gas and the displayed leak rate match the data of the
calibrated leak. If the leak rate does not match, select “Leak rate change” and
correct the value.
5. Select “Start.”
6. Hold the sniffer tip into the center of calibrated leak opening and follow the
instructions in the display. If you have to wait until the air signal has stabilized then
this can take up to 30 seconds with a helium or hydrogen calibration.
7. Confirm the new values with the button on the bottom right.
6.4.3 Gas equivalent to helium and hydrogen, settings for
diluted gas
If you are looking for helium or hydrogen, you can have also have the determined leak
rate for the gas equivalent displayed, e.g.as R134a.
If you have an equivalent set, all displays will show the original gas followed by the
equivalent in brackets. For example: He (R134a)
Proceed as follows to set a gas equivalent:
1. Select helium or hydrogen from the gas library.
2. Select the “Status” line in the “Settings gas …” window and press “Change.”
3. Select “Equivalent name” in the window that opens. The gas library will be
displayed again.
4. Select the equivalent name and confirm with “OK.”
