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 buttons in 100, 10 or 1 count increments. See Figure 3-8 for pin assignments and diagram of the analog output connector.
