PN 9000-165-VE, Rev P
All measurements require a two-point calibration: span and zero, so
the zero will always be performed.
Calibrations are only allowed when the sensor is in Normal mode.
Check the Status Bar at the bottom of the HOME screen if you are
unsure of the sensor’s status.
If you do not select a gas to calibrate, a warning displays indicating
that no gas was selected. Press CANCEL to exit the screen.
After a calibration is completed and if you have replaced the analyzer
cell since the last calibration, you will see a yellow screen indicating that
a cell change has been detected and asking if you would like to reset the
Cell Age. If you would, navigate to “Yes” and press ENTER/MENU. If you
would not, navigate to “No” and press ENTER/MENU.
