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.
