How to recalibrate the

Removal of the
internal calibrated leak
It enables the auto-
calibration of the detector.
Autocalibration is triggered
at start-up or when the
button is pressed on
the control panel (see
C 30
).
AUTOCAL
The frequency of preventive maintenance is listed
in D 10.
In order to ensure the reliability of the helium test,
ALCATEL recommends to "recalibrating" the internal calibrated
leak at least every 2 years (from the calibration date marked
on the leak label and its calibration certificate).
Recalibration is generally performed using a comparative
method with a reference standard. This work can only be
performed in ALCATEL or other approved service centers.
For this, therefore it is necessary to remove the internal
calibrated leak from the detector.
- Switch off the detector and disconnect it from the main
power.
- Open the front cover of the detector (attached with 4
screws).
- Disconnect the heat sensor connector (3-pin connector).
- Disconnect the DN 16 flange and remove the calibrated
leak.
Caution: Do not separate the heat sensor from the
calibrated leak.
