7.2.3.4. Zero Calibration
The zero calibration allows the instrument to calibrate it’s internal ozone offset factor. This should only be done with a source of zero air connected to the “Sample In” port of the M465M. Allow the instrument to stabilize on the zero air source before attempting to zero. This normally takes
If the zero calibration is enabled, the internal ozone offset factor will automatically be reported as zero every 6 minutes. If the zero calibration is disabled, then manual calibration is necessary based on the customer’s applications. For normal applications, the zero calibration is not necessary.
When entering the Zero Calibration menu, the prompt “ENT TO CAL” appears on the display. Simply confirm the calibration by pressing the ENT button to perform the calibration (to abort the calibration, press and hold the CFG button to return to the previous menu level.) After pressing ENT, the instrument will automatically exit the menu mode and return to Concentration mode. The concentration reading should quickly go to zero.
