Stopping a Gas Alarm
The Low and High Alarms stop when the ambient gas level
returns to the acceptable range.
Note: If alarms are set to latch, press
C
to reset the alarms.
The detector computes the TWA value based on an 8-hour
workday, and the STEL alarm based on a 5 to 15 minute
period (user selectable). See “
STEL Calculation Period ”.
To clear the TWA, STEL and maximum gas exposure
readings, press
C
and
G
simultaneously.
Sensor Alarm
The detector tests for a missing or defective sensor during
the activation self-test. See the section “
If the Detector Does
Not Work ”.
Low Battery Alarm
The detector tests the batteries on activation and
continuously thereafter. Battery power is continually
displayed during normal operation. If the battery voltage is
low, the detector activates the Low Battery Alarm.
The Low Battery Alarm continues until you replace the
batteries or the battery power is almost depleted. If the
battery voltage drops too low, the detector executes an
Automatic Shutdown.
Automatic Shutdown Alarm
If the battery voltage is in immediate danger of dropping
below the minimum operating voltage, the audible alarm
beeps 8 times and the visual alarm flashes 8 times. After
3 seconds, the display blanks out and the detector stops
normal operation. The display shows
LOW periodically
until the battery power is depleted.
Replace the batteries. See the section “ Replacing the
Batteries ”.
Note: If the Confidence Beep is ON, the audible alarm does
not beep during a Low Battery alarm. See the section
“
Confidence Beep ”. Typically, the Low Battery Alarm
continues for 30 minutes before Automatic Shutdown.
