Alarm Screen
In the presence of a gas concentration that
exceeds the low or high level threshold, the
instrument will alarm. New alarm
detection in any of the instrument’s normal
operating screens – the battery life, peak, or
initiate print screens – will force a
transition back to the monitoring screen.
An alarm is indicated on the display by the
Alarm Indicator and either the Up Indicator
or Down Indicator which designate either
high or low alarm, respectively.
Sample High Alarm Screen
Battery Failure
When the instrument reaches the end of its
useful life, the word FAIL will appear on
the instrument’s display and both the
audible and visual alarms will be activated;
the unit should be removed from service
immediately.
The unit will remain in this
alarm state for 10 minutes; during this
time, it will no longer detect gas. After 10
minutes in this alarm state, the words "call
ISC" will appear on the display and both
the audible and visual alarm will cease.

System Error or Sensor Missing
The GasBadge Plus performs a self-test
without initiation from the operator. The
self test occurs at intervals of 2 seconds.
The self test ensures the presence of the
sensor and validates the software process. A
system exception is generated if the sensor’s
presence cannot be confirmed or if an error
is detected.
Sensor Missing Error Screen
If the sensor becomes disconnected from the board, the GasBadge Plus enters the
Sensor Missing Error screen. The gas type is displayed on the auxiliary readout,
the word “FAIL” will be on the primary readout, and the Warning icon will be
