Responding to Battery Alarms
WARNING: The SC-01 is not operational as a gas monitoring device
during a dead battery alarm. Take the SC-01 to a non-
hazardous area and change the alkaline batteries as
described in “Replacing the Batteries” on page 33.
The SC-01 is fully functional in a low battery warning condition. However,
only about eight hours 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. See “Replacing the Batteries” on page 33” for instructions to
change the batteries.
Responding to a Sensor Failure Alarm
1. Try to calibrate the SC-01 as described in “Performing a Fresh Air
Adjustment” on page 23 and “Performing a Span Adjustment” on
page 24 before replacing the sensor.
2. If the sensor failure continues, replace the sensor as described in
“Replacing the Sensor” on page 34.
3. If the sensor failure condition continues after you have replaced the
sensor, contact RKI Instruments, Inc. for further instructions.
