Select the hard vacuum
test mode (

While the leak detector is in stand-by,
Connect the part to be tested to the leak
connect the sniffer probe (accessory to be

purchased separately) to the sniffer port of
chamber connected to the leak detector.

The detector returns automatically to stand-by mode.
If Memo function is activated and a printer is connected to the detector,
a test ticket will be printed automatically after the test (
MAIN FONCTIONS

Set Points

C 401
2 adjustable set points:
 reject set point in hard vacuum,
 reject set point in sniffing.
Define the acceptance threshold of the good/bad parts:
 leak value measured ≤ reject set point => part accepted.
leak value measured > reject set point => part rejected.


Audio alarm set points

C 401
Digital voice informs the operator about the detector state or the actions to do.
The audio alarm informs the operator that the reject set point was crossed. The level
varies from 0 to 8 (0 to 90 dB).
or
Stop simultaneously the audio alarm and the digital voice with the key

Autocalibration

C 406
It allows to check that the detector is adjusted to detect the selected tracer gas and dis-
play a correct leak value.
By default, autocalibration is set ON and the internal calibrated leak is selected to allow
a quick leak detector autocalibration.
Autocal = ON : the detector will be automatically calibrated at each switching on.
At any time, the operator can start an autocalibration (
