Description of the Related Art In general, various analyzers such as a gas analyzer are required to perform measurement in order to correct an error caused by a temperature drift or a change with time of a detection unit and an amplification unit. Prior to the measurement work, it is necessary to perform zero adjustment and span calibration of the analyzer.
