Gas Tracer Operator’s Manual, CSA Version
NOTE:
With ALRM SLNC set to OFF in Maintenance Mode, you cannot silence
the buzzer while the gas reading is above (below for an oxygen Low
Alarm) the low alarm setting.
Responding to Alarms
This section describes response to gas, over range, battery, and sensor failure
alarms.
Responding to Gas Alarms
1. Determine which gas alarm has been activated.
2. Follow your established procedure for an increasing gas condition or a
decreasing oxygen condition.
3. If necessary, reset the alarm using the RESET SILENCE button once the alarm
condition has been cleared.
Responding to Over Range Alarms
WARNING:
An over range alarm may indicate an extreme combustible gas,
toxic gas, or oxygen concentration. Confirm a normal condition
with a different Gas Tracer or with another gas detecting device.
CAUTION:
High off-scale readings may indicate an explosive concentration.
PRUDENCE:
Des lectures élevées hors échelle peuvent indiquer une concentration
explosive.
1. Determine which gas alarm has been activated.
2. Follow your established procedure for an increasing gas condition.
3. Reset the alarm using the RESET SILENCE button once the alarm condition
has cleared.
4. Calibrate the Gas Tracer as described in the calibration section of this manual.
5. If the over range condition continues, you may need to replace the 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 162.
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 162.
NOTE:
Alarms and the back light feature consume battery power and reduce
the amount of operating time remaining.
