It is recommended to use this function when the background noise of the detector is high
1. Check that the detector is in ‘Stand-by’ mode.
2. Check that the inlet vent is “automatic.”
3. From the Settings screen, press [Test] [Regeneration].
4. Install a blank-off flange on the detector’s inlet port.
5. Press [Start].
–
Regeneration stops automatically after 1 hour.
6. To stop regeneration before the automatic stop time, press [Stop] or the START/STOP key.
–
Start a test (‘Zero activation’ function not enabled) to check that the detector is no longer pol-
luted.
After regeneration, the inlet vent configuration is the same as it was before regeneration.
8.2.9 Massive Mode
This mode allows the detector to perform a test (
4
He only) on a very large leak when the detector has
not shifted to Gross Leak Mode and remains in roughing.
Massive mode can only be used if an external gauge is selected (see chapter “External gauge”):

limit

Active To be selected
Prerequisites for the detector to shift automatically into Massive mode:
● function enabled
● pressure < 100 hPa
● pressure stabilized for at least 30 s
A message informs the use that the detector has shifted automatically into Massive
mode.
The detector can then perform a qualitative test of a leak (information leak > 50 mbar
· l/s (5 Pa · m
3
/s) only).
The maximum use time is 55 minutes.

Sensitivity To be selected
● High = large volume test (default configuration, recommended)
● Low = test on volume < 1 l (if necessary)

8.2.10 Calibration check
Calibration check allows the user to save time because this operation is faster than full calibration.
The calibration check is performed with the leak detector’s internal calibrated leak (leak type parameter
= ’internal’).
Calibration check is enabled if the calibration is set to ‘Check at start’ (see chapter “Calibration func-
tion”).
