6.9.4.2. Analog Output Calibration Mode
The analog outputs can be calibrated automatically or manually. In its default mode, the
instrument is configured for automatic calibration of all channels. Manual calibration should be
used for the 0.1V range or in cases where the outputs must be closely matched to the
characteristics of the recording device. Outputs configured for automatic calibration can be
calibrated as a group or individually. Calibration of the analog outputs needs to be carried out on
first startup of the analyzer (performed in the factory as part of the configuration process) or
whenever re-calibration is required.
