Programming New Gasses
As new refrigerants come into use the HGM-MZ allows the addition of these new gases to its on-board
refrigerant gas library. At the end of the gas library list is an option labeled CUSTOM for adding new gases.
From the Calibration Screen use the LEFT/RIGHT arrows to select CUSTOM from the list of refrigerants.
Next, press ENTER, and use the UP/DOWN arrow keys to enter the calibration factor. The selection of the
matching gas and CAL factor is performed by Bacharach by analyzing the new refrigerant. Once the matching
gas is determined, field calibration is possible by using the same procedure as for other refrigerants. When
the new gas entry is complete simply setup the appropriate zone for CUSTOM.
Program the instrument for a new gas as follows:
1. From the Calibration Screen, use the PREV GAS or NEXT GAS options to scroll through the list of
available choices until the CUSTOM option is displayed.

2. Select the CUSTOM option. Press ENTER to accept the new entry or ESC to revert to the previous
setting.
3. Enter the new CAL Factor as received from Bacharach.
