4.13.6. ANALOG OUTPUT CALIBRATION
Analog calibration needs to be carried out on first startup of the analyzer (performed in
the factory as part of the configuration process) or whenever recalibration is required.
The analog outputs can be calibrated automatically, either as a group or individually
(Section 4.13.6.1), or adjusted manually (see Section 4.13.6). (Manual calibration should
be used for the 0.1V range or in cases w
here the outputs must be closely matched to the
characteristics of the recording device. Manual calibration requires the AUTOCAL
feature to be disabled).During automatic calibration the analyzer tells the output
circuitry to generate a zero mV signal and high-scale point signal (usually about 90% of
chosen analog signal scale) then measures actual signal of the output. Any error at zero
or high-scale is corrected with a slope and offset.
To enable or disable the Auto-Cal feature for one output channel, press.

calibrated manually.
