External
calibrated leak
Recalibration
An external calibrated leak (defined in accordance to your own
requirements)
is required for the external calibration procedure.
Accessories A
700
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:
•
l
st
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.
