Note 1: When measuring 4 components, or NOx, SO2, CO and O2 (with 2 infrared gas analyzers), output is held by using the external hold function at the time of automatic calibration.
Note 2: In the setting mode, output is held indifferently to the ON/OFF status of hold setting.
Note 3: In case the analyzer is equipped with a maintenance switch, output is held while the switch is turned on.
