Tested by Intertek to UL 2075 for Sensitivity, Selectivity, and Electrical Supervision at 23 ±3
°C (73 ±5°F) and 50 ±20 %RH
Sensor Over Range
• Sensor over range occurs whenever the detected gas
concentration level is higher than the full scale value of the sensor.
• When an over range condition occurs, the LCD displays
"OVRRANGE" and the buzzer sounds for 50 milliseconds, once
every 10 minutes.
• The LED blinks once per second normally but twice per second
during an over range condition.
• When the gas concentration falls back within the full scale range
of the cell, the the buzzer is silenced and the LCD displays the
current concentration.
