Zero Sensor (Menu Mode C:1):
This calibration feature allows the instrument to determine the sensor output under
zero gas conditions.
•
Apply zero gas (zero grade/UHP Nitrogen) to the sensor inlet and allow enough
time for the sensor to respond and all the gas to be purged (typically 2 minutes
minimum dependent upon flow rate).
•
Select menu mode
C: 1
and press ENTER.
•
Press ENTER to perform the ZERO calibration. Pressing MENU instead of
ENTER aborts the calibration (the ZERO factor will still be displayed on exit).
•
Press MENU – the display will show the ZERO factor for the instrument before
returning to its standard mode of operation.
The ZERO factor should be recorded on any calibration certificates completed.
