M703E Calibrator Operator’s Manual Operating the M703E Calibrator
6.9.2. TEST CHANNEL CALIBRATION
TEST CHANNEL 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.
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 via the
AOUTS CALIBRATION command, or by using the CAL button
located inside
TEST_CHANNEL submenu. By default, the analyzer is configured so that calibration of TEST
CHANNEL
can be initiated with the AOUTS CALIBRATION command.
