Description
Alarm occurs when, if attached, the pump is not
operating correctly. While in alarm, every ten
seconds the monitor attempts to restart the
pump. If unsuccessful, the monitor remains in
alarm.
Note: The nominal flow rate is >200 cc/m (.2
LPM). A pump fault alarm will occur when
the flow is less than 200 cc/m +0, -25%.
Alarm occurs when the monitor's battery
reaches a low level of charge or is nearing its
end of life.
This alarm occurs when there is not enough
battery life remaining for continued operation.
The battery must be charged or replaced.
The instrument is NOT detecting gas at this
time.
Alarm occurs when one or more sensors are
due for a bump test. If the monitor settings
permit, an in-field bump test may be performed
in an area known to be nonhazardous.
Alarm occurs when one or more sensors are
due for calibration. If the monitor settings
