The purge bag needs to be filled with fresh/clean air failure to do so can result in wrong ppm readings

After the bag has been filled with air it will last for approximately 40 minutes of normal operation after
that time the bag needs to be filled again, press the ENTER button to start the refill process ensure that
it is filled with clean/fresh air.
After the air bag has been filled successfully, the monitor starts or resumes normal operation by
displaying the Data Display Screen Measure.

at the same time. Next, use the Keypad buttons to move the arrow (>) until it points to the desired
function, and then press the

button to select that function.
If a system malfunction occurs the front panel
FAULT
light will flash and the audible alarm, if activated
will start beeping.
The
FAULT
light and audible alarm will automatically turn OFF after the cause of the fault has been
eliminated.
Pressing the
SILENCE
button while a fault condition still exists causes the internal audible alarm to
turn OFF for a period of time as set by the

FAULT
menu will appear which contains records of the last 30 fault events. The most recent
event is displayed when the Fault screen is first displayed. After 30 events have been recorded, the
newest record overwrites the oldest. Each record lists an event’s numeric fault code plus the date and
time at which the event occurred. If the fault is still present when the FAULTS function is selected, then
the current cause of the fault is displayed If the cause of the fault has been cleared, then the Faults Log
screen will show <0000> along with the date and time the fault was cleared, see fault table below for
troubleshooting.
The cause of the fault is identified by a numeric fault code. To convert the fault code into a text
description of the fault, first press the ENTER button and then use the Keypad buttons to scroll
through the display until the text description of the fault appears. If the fault code is a combination of
two or more faults, then continue to use the Keypad buttons until all fault text descriptions have been
displayed. For example, the fault code <1800> represents the summary of both a Sample Flow <0800>
and a Purge Flow <1000> fault as shown to the left.
