Setting Alarms
The alarms can be adjusted over the full scale range, and they are set
as a percent of full scale. Thus, an alarm set to indicate 9.6 on the display
while on the 10% O
2
range will activate at 9.6% O
2
on the 10% O
2
range
and at 2.88% O
2
on the 3% O
2
range (96% of full scale). To set the alarms:
1. Place the range switch located below the front panel display in
the 10% range position (or highest range available).
2. Place the power switch in the ON position.
3. To set the high alarm, hold down the SET HI ALARM button
while turning the potentiometer to the right of the button until
the display reads the desired concentration.
4. To set the low alarm, hold down the SET LO ALARM button
while turning the potentiometer to the right of the button until
the display reads the desired concentration.
5. Remember, the System/Cell Failure alarm is factory set at 2%
of full scale; should this alarm trigger, the LED to the left of the
front panel display will blink.
