4.13.6.2. Manual Calibration of Analog Output 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.
Calibration is performed with a voltmeter connected across the output terminals (See
Figure 6-14) and by changing the actual output signal level using the front panel keys in
100, 10 or 1 count increments.
