Halogen Gas Monitor – MultiZone Remote Display
Instruction 3015-5157 45
Service Mode
When activated, the Service Mode will disable a specific HGM-MZ unit for a specified length of time. The
default is 60 minutes. This time interval can be changed as described in the Service Timeout section on Page
26.
IMPORTANT: Note that while in the Service Mode, no measurements are made, nor are alarms activated.
(I couldn’t get this to work, so I need definition on this section.)
From the System Screen, select the HGM unit you wish to place into Service Mode. On HGM Setup Screen
#1, select SERVICE MODE ENTRY. An option will appear to continue to “IN SERVICE” or to “QUIT”. To
continue to IN SERVICE, select that option and press the ENTER key twice within 3 seconds.
Note that the System Screen will display which monitors are in the Service Mode.
To exit the Service Mode, select QUIT.
