6.13.4.2. 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.
