that has triggered the over range alarm.
6. 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 GX-2012 is not operational as a gas monitoring device
during a dead battery alarm. Take the GX-2012 to a non-
hazardous area and replace or recharge the batteries as
described in “Replacing or Recharging the Batteries” on
page 146.
The GX-2012 is fully functional during a low battery warning. However,
only a limited amount of operating time remains, approximately 1 - 2 hours.
The amount of time depends on how often the LCD backlight is used and
how often the unit is responding to alarm conditions. Recharge the battery
pack or replace the alkaline batteries as soon as possible as described in
“Replacing or Recharging the Batteries” on page 146.
NOTE: Alarms and the back light feature consume battery power and
reduce the amount of operating time remaining.
Responding to Sensor Failure Alarms
1. Determine which sensor has triggered the sensor failure alarm.
2. Try calibrating the sensor first, as described in “Calibration Mode” on
page 57 before replacing it.
3. If the sensor failure continues, replace the sensor as described in
“Replacing a Sensor” on page 154.
4. If the sensor failure condition continues after you have replaced the
sensor, contact RKI Instruments, Inc. for further instructions.
Responding to Clock Failure Alarm
This alarm occurs if the internal unit date has been changed to something
unreasonable like 15/34 (month/day).
1. Press and release the RESET SILENCE button to continue into normal
operation.
CAUTION: There will be no datalogging function if you operate the
instrument after a clock failure.
