Then, the procedure is the same as for the automatic internal
calibration.

C 302
Internal calibration
with an external
calibrated leak
It is semi-automatic because the operator must connect a calibrated
leak to the inlet port of the detector.
•
At the starting of the detector:
The calibration is not start even if the autocal is ON. The operator is
informed that the calibration requests a calibrated leak connected to
the inlet port of the detector.
•
On operator request:
The operator can start a calibration whenever the leak detector is not
in test mode.
Note: Internal calibration set ON.
Tickets If a printer is connected to the leak detector, a ticket is automatically
printed at the end of the calibration: example
3
B 320.
Procedure
1
Gas selection
In standard the gas used is the Helium 4.
With the 3 masses option, the operator can use
different gases: Helium 3, Helium 4 or Hydrogen.
