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 EAGLE 2 or with another
gas detecting device.
1. Determine which channel is in alarm.
2. Follow your established procedure for an extreme gas condition.
3. Reset the alarm using the POWER ENTER RESET button once the alarm
condition has cleared.
4. Calibrate the EAGLE 2 as described in “Chapter 4: Calibration Mode” on
page 55.
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 EAGLE 2 is not operational as a gas monitoring device
during a dead battery alarm. Take the Model EAGLE 2 to a
non-hazardous area and replace or recharge the batteries as
described in “Replacing or Recharging the Batteries” on
page 72.
The EAGLE 2 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 Ni-MH
batteries or replace the alkaline batteries as soon as possible as described in
“Replacing or Recharging the Batteries” on page 72.
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 sensor first, as described in “Chapter 4: Calibration
Mode” on page 55 before replacing it.
