Responding to Over Range Alarms
WARNING:
An over range condition may indicate an extreme combustible gas,
toxic gas, or oxygen concentration. Confirm a normal condition with a
different GX-6000 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 channel is in alarm.
2 . Follow your established procedure for an extreme gas condition.
NOTE:
If your instrument has both a low range PID sensor and a high range PID sensor
installed and if you are monitoring for gases in the higher range, the low range
PID channel may be in over range alarm while monitoring, depending on the
level of VOCs present.
3 . Reset the alarm using the RESET button once the alarm condition has cleared.
4 . Calibrate the GX-6000 as described in “Chapter 4: Calibration Mode” on page 69.
5 . If the over range condition continues or if you are not able to successfully calibrate
the unit, 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 GX-6000 is not operational as a gas monitoring device during a
dead battery alarm. Take the Model GX-6000 to a non-hazardous area
and replace or recharge the batteries as described in “Replacing or
Recharging the Batteries” on page 102.
The GX-6000 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 Li-ion battery pack or replace the alkaline batteries as soon as
possible as described in “Replacing or Recharging the Batteries” on page 102.
NOTE:
Alarms and the LCD back light 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 failed sensor, as described in “Chapter 4: Calibration Mode” on
page 69 before replacing it.
3 . If the sensor failure continues, replace the sensor as described in “Replacing a
Sensor” on page 113.
4 . If the sensor failure condition continues after you have replaced the sensor, contact
RKI Instruments, Inc. for further instructions.
