sensor 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 Gas Tracer is not operational as a gas monitoring
device during a dead battery alarm. Take the Gas Tracer
to a non-hazardous area and replace or recharge the
batteries as described in “Replacing or Recharging the
Batteries” on page 178.
The Gas Tracer 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 178.
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 61 before replacing it.
3. If the sensor failure continues, replace the sensor as described in
“Replacing a Sensor” on page 187.
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.
2. Attempt to change the date using the DATE menu time in
