6.13.6. 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 re-calibration is required.
The analog outputs can be calibrated automatically or adjusted manually (see Section 6.13.5). 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.
Automatic calibration can be performed a group via the
AOUTS CALIBRATION command, or individually by
using the
CAL button located inside each output channels submenu. By default, the analyzer is configured so
that calibration of all four of the outputs can be initiated with the
AOUTS CALIBRATION command.
To enable or disable the Auto-Cal feature for one output channel, press.
