Calibration
No span calibration is required for the IR bench. An
automatic zero reference calibration is performed at startup
and then every 24 hours.

specified, except for interference specified in the table “Interfering gas and vapor effects” below.
The accuracy specification is not valid if more than two agents are present in the gas mixture. If
