Operation
- Plug OA-1 into 120 VAC outlet.
- The alarm will engage immediately upon powering it up - This is because the sensor
needs to warm up. Initial warm up may take from 30 minutes to 1 hour - 12 hours for
full warm up.
- After 30 minutes of warm up, press the brown button on the circuit board inside to
perform a zero calibration, make sure this is done in an ozone free environment.
- After 12 hours of warm up, perform a zero calibration once more.
- Set ozone alarm set point – The dial in the upper right corner is 100% of sensor range.
Example - If sensor range is 1 ppm, and the alarm is to be set at .1 ppm, the dial will be
set to 1.
