The Calibration Screen
Overview
The Calibration Screen is used to adjust the calibration factor for each refrigerant gas. It is also used to
program the instrument for new gasses.
IMPORTANT: Changing information on CAL FACTORS will VOID the factory calibration. Typically, the unit
will remain within the factory-calibrated accuracy indefinitely and no calibration is required. Complex software
algorithms adjust for temperature drift, IR source aging, and pressure changes in order to keep the unit within
factory accuracy specifications.
Navigating to the Calibration Screen
On the System Screen, select the target HGM-MZ unit and access that monitor’s Setup Screen #1. Then
select the CAL option to go to the selected monitor’s Calibration Screen.

Adjusting Calibration Factor
The factory default cal factor for standard units is 1.000. This value may be different if the high accuracy
option is ordered.
Modifications to calibration must be done on each monitor. If calibration is attempted from the RD unit, the
“Use monitor front panel interface to adjust calibration” message is displayed.
