Responding to an Over Range Alarm
WARNING: An over range condition may indicate an extreme toxic
gas or oxygen concentration. Confirm the gas
concentration with a different 03 Series or with another
gas detecting device.
1. Follow your established procedure for an increasing gas condition.
2. Reset the alarm by pressing and releasing the POWER MODE button
after the alarm condition has cleared.
3. Calibrate the 03 Series as described in “Calibration Mode” on page 31.
4. If the over range condition continues, replace the sensor as described
in “Replacing the Sensor” on page 66.
5. 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 03 Series is not operational as a gas monitoring
device during a dead battery alarm. Take the 03 Series to
a non-hazardous area and change the alkaline batteries
as described in “Replacing the Batteries” on page 64.
The 03 Series is fully functional in a low battery warning condition.
However, only a couple of days of operation may remain depending on
certain conditions such as alarm occurrences and how often the backlight
comes on.
NOTE:
Alarms and the back light feature consume battery power and
reduce the amount of operating time remaining.
When a low battery warning occurs, change the batteries as soon as
possible. Refer to the instructions in “Replacing the Batteries” on page 64
for more information.
Responding to a Sensor Failure Alarm
1. Try calibrating the 03 Series as described in “Calibration Mode” on
page 31.
2. If the sensor failure continues, replace the sensor as described in
“Replacing the Sensor” on page 66.
3. If the gas sensor failure condition continues after you have replaced the
gas sensor, contact RKI Instruments, Inc. for further instructions.
