Recalibration
An external calibrated leak (defined in accordance to your own
requirements) is required for the external calibration procedure.

It is recommended to have each calibrated leak recalibrated at regular
intervals to validate its value.

Digital and
analog display
When the external calibration is performed, the digital display will show a
corrected value. Then
COR
will come on to reflect it. The analog display
in the remote control is not corrected and therefore both values might be
different.
External calibration
procedure
The external calibration should only be performed when the leak
detector is already internally calibrated.
The external calibration procedure is performed in 2 steps:
•
lst step: selection of the test mode (hard vacuum or sniffing)
•
2nd step: adjustment of the target value: see below.
External calibration
cancellation
At any time, the operator can cancel external calibration procedure.
COR
Procedure Note: The external calibration should be performed in the test mode
used by the operator: if the operator uses both test modes (hard
vacuum and sniffing), he should perform one external calibration
when he works in each test mode.
The external calibrated leak is connected to the inlet port of the leak
detector or at a suitable location of the installation to test.
