Function Screens - Bacharach Halogen Monitor Instruction

Operation
During normal operation, the Data Display screen shows when the monitor is performing the following
two functions:
MEASURE indicates that the monitor is actively measuring gas. In the screen shown above, 10 ppm of
R-134A gas is currently being detected, and that a peak measurement of 20 ppm has occurred sometime
in the past. The measurement cycle runs for 4 minutes.
To reset the peak value to zero, press the ENTER button.

2.9.4 Function Screens

The Function screens are used to set up the monitor and display stored data.
From the Data Display screen, press both the Keypad Left and Right buttons at the same time to
display the first Function Menu screen. Next, use the Keypad buttons to move the arrow (>) until it
points to the desired function, and then press the ENTER button to select that function.

Once a function has been selected, use the Keypad to scroll through the displayed data or to change a
parameter associated with that function. Press ENTER to save any newly entered parameters. Press the
ESC button to return to the previous screen without saving.
Note that if no buttons are pressed within 90 seconds after selecting a function, the unit returns to the
Data Display screen.
FILLBAG
– Press ENTER to manually fill the purge-air bag.
WARNING:
environment that is at the same temperature and humidity as
the area being checked for gas. DO NOT fill the bag in an
area that is contaminated with gas.
EMTYBAG
– Press ENTER to manually empty the purge-air bag. Use
this function to drain the bag if it becomes contaminated with gas.
ALRMLVL
– Detected gas level that causes the front panel ALARM
(red) light to turn ON and the audible alarm to sound (if AUDALRM
function is set to ALARM or ALARM/FAULT).
AUDALRM
– The internal audible alarm is programmable to function as
follows:
• OFF – Audible alarm is disabled.
• ALARM – Alarm sounds when detected gas level exceeds the
ALRMLVL level as evidenced by the front panel ALARM (red) light
turning ON.
• ALARM/FAULT – Alarm sounds when either the detected gas level exceeds the ALRMLVL value, or if
a system fault occurs, as evidenced by the front panel ALARM (red) light or FAULT (yellow) light
turning ON.
• LEAK DETECTOR – When selected, the monitor will produce a leak detector type of audible
feedback. At zero ppm there will be a tic every 2 seconds with the tic rate increasing up to 20 tics per
second when the ppm level reaches the ALRMLVL setting.
