General
notes
(in
vacuum
or
sniffing
test mode)
•
During the external calibration process:
basic digital display x
VACUUM/SNIF COR
= target value
Basic
digital display is the helium signal basic display without
correction ratio (as if COR indicator is
OFF
or VACUUM/SNIF COR
equal to
1
.00E-00).
•
Once the external calibration correction is validated, the
digital
display is modified:
corrected
digital display = basic digital display x
VACUUM/SNIF
COR
The
analog display (standard
scale)
always displays the basic value of
the helium signal which is not modified by VACUUM/SNIF COR.
•
During the last step of the external calibration, the
V
ACUUM/
SNIF
COR is displayed and automatically calculated with
respect
to
the fixed target value and the
present
basic signal value.
The
VACUUM/SNIF COR ratio is fixed and memorized when the
AUTOCAL
key is
pressed
to confirm the
CORRECTION
and stop the
external calibration process.
•
The
COR indicator is ON as soon as the VACUUM/SNIF COR is
ON and different from
1
.00E-00.
If the target value is the
same
value as the standard signal on the
digital display, in other word if VACUUM/SNIF COR is equal to
1.00E+00, the COR indicator is automatically OFF: the external
calibration is
OF
F
.
•
If
RESET
is
pressed
during or at the last step of the external
calibration
process,
the leak
detector comes
back to the previous
digital display
status
which was
effective
before the external
calibration
request
and VACUUM/SNIF COR is not changed.
