4.9.2.3. Manual Calibration of the TEST Channel 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 4.9.2.1)

Calibration is performed with a voltmeter connected across the output terminals (See

Figure 4-2) and by changing the actual output signal level using the front panel menu

buttons in 100, 10 or 1 count increments.
