Data Display Screen
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, 0 ppm of gas
is currently being detected. The measurement cycle runs for 4 minutes.
PURGE
is displayed when the monitor is resetting its infrared detector to a baseline of 0 ppm using the air
stored in the internal purge-air bag. The purge cycle runs for 10 seconds. The monitor will operate for
approximately 30 minutes before the purge-air bag needs refilling.

Function Screens
The Function screens are used to display stored data and to set up the monitor.
From the Data Display screen, press both
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. Normal fill
time is less than 180 seconds. (3 minutes)
WARNING: Fill the purge-air bag in a clean, fresh-air environment that is at
the same temperature and humidity as the area being check for gas. DO NOT
fill the bag in an area that is contaminated with sulfuryl fluoride gas.
EMTYBAG – Press ENTER to manually empty the purge-air bag. Use this
function to drain the bag if it becomes contaminated with gas. NOTE: THE
BAG MUST BE COMPLETELY EMPTY PRIOR TO SHIPPING TO AVOID
DAMAGE
ALRMLVL – This is the detected gas level at which the unit goes into a
gas-alarm state, as indicated by the front panel ALARM light turning ON.
Factory set at 5 ppm.
AUDALRM – The monitor’s internal audible alarm is factory set to activate
at the gas-alarm level of 5 ppm. The audible alarm is programmable to
function as follows:
