sensor.
5. If the over range condition continues after you have replaced the
sensor, contact RKI Instruments, Inc. for further instructions.
Responding to Battery Alarms
WARNING: The Model GP-01 is not operational as a gas monitoring
device during a dead battery alarm. Take the Model GP-01
to a non-hazardous area and change the alkaline
batteries or charge the Ni-cad battery pack as described
in “Replacing or Charging the Batteries”.
The Model GP-01 is fully functional in a low battery warning condition.
However, only a limited amount of time remains for operation,
approximately 30 minutes when using the Ni-cad battery pack or 2 hours
when using alkaline batteries. The amount of time depends on how often
the LCD backlight is used and how often the unit is responding to alarm
conditions.
NOTE: Alarms and the back light feature consume battery power and
reduce the amount of operating time remaining.
When a low battery warning occurs, change or charge the batteries as
soon as possible. Refer to the instructions in “Replacing or Charging the
Batteries” for more information.
Responding to a Sensor Failure Alarm
1. Try calibrating the Model GP-01 first, as described in “Calibration”,
before replacing the sensor.
2. If the sensor failure continues, replace the sensor as described in
“Replacing the Combustible Sensor”.
3. If the gas sensor failure condition continues after you have replaced the
gas sensor, contact RKI Instruments, Inc. for further instructions.
Responding to a System Failure Alarm
1. If a system failure occurs, try turning the unit off then on again.
2. If the unit remains in system failure, contact RKI Instruments, Inc. for
further instructions.
