Operating the M703E Calibrator M703E Calibrator Operator’s Manual
6.9.2.3. 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 Section6.9.2.1)
Calibration is performed with a voltmeter connected across the output terminals (See Figure 6-2) and by
changing the actual output signal level using the front panel keys in 100, 10 or 1 count increments.
