6 No entries are required during the running calibration phase.
7 In the last step, the Modul1000 saves the newly determined calibration factor.
If the newly determined calibration factor deviates from the prior calibration factor by
the factor 2, the new value has to be acknowledged by acceptance.
Press "Yes" and the newly determined calibration factor will be taken over.
Press "No" and the newly determined calibration factor will not be taken over. The
Modul1000 will further use the calibration factor determined in the prior calibration
procedure.

External automatic
This requires the connection of an external test leak with solenoid valve.
Once this procedure is started the entire procedure is performed automatically. At the
end (after about 25 s) a beep is released. Thereafter the leak detector is ready for
further use.
It is possible to set the time before the test leak is opened/closed to receive a
constant measuring signal.

1 Make sure that the test leak is connected and opened.
2 Check the leak rate printed on the test leak and compare it with the leak rate at the
display. If the leak rates are not identical press Edit leak rate and correct the value.
If the leak rates are the same, press START.
3 The bargraph display shows a signal which must not vary much. If so, please press
OK.
4 Close the external test leak and confirm with OK.
5 The bargraph display shows a signal which must not decrease any more. There
might be a small fluctuation which is okay. There If so please press OK (Soft Key no.
8).
⇒ The Modul1000 displays the old and the newly calculated calibration factor.
