5.9.3.6. MANUAL CALIBRATION OF THE ANALOG OUTPUTS CONFIGURED FOR
VOLTAGE RANGES
For highest accuracy, the voltages of the analog outputs can be manually
calibrated.
Note
The menu for manually adjusting the analog output signal level will only
appear if the AUTO-CAL feature is turned off for the channel being adjusted
(See Section 5.9.3.3).
Calibration is performed with a voltmeter connected across the output terminals
and by changing the actual output signal level using the front panel touchscreen
in 100, 10 or 1 count increments. See Figure 3-7 for pin assignments and
diagram of the analog outp
ut connector.
