(to 95% stated accuracy)
Calibration Front mounted potentiometers
Over range If the measured gas concentration exceeds the
calibration range of the sensor, the display will
indicate FAULT
Pellistor protection The supply to the gas sensing element will be
switched off to prevent oxidisation damage
occurring if the gas concentration exceeds safe
limits. The sensor will remain switched off until
reset.
