MAINTENANCE AND CALIBRATION
During maintenance, you must perform the calibration and functional test, see below, in addition to the inspection. A fixed

For an SC2 sensor, if this interval is exceeded, a digital maintenance message is generated and transmitted. Performing
calibration automatically clears this message.
