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 192 on the display while on the 200 PPM O2 range will activate at 192 PPM O2 on the 200 PPM O2 range and at 1920 O2 on the 2000 O2 range (96% of full scale). To set the alarms:
1.Place the range switch located below the front panel display in the 2000 PPM 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.
