5.9.3.3. MANUAL ANALOG OUTPUT CALIBRATION AND VOLTAGE ADJUSTMENT
I
MPORTANT
112
For highest accuracy, the voltages of the analog outputs can be manually calibrated.
Calibration is done through the instrument software with a voltmeter connected across
the output terminals (refer to Figure 5-23). Adjustments are made using the control
buttons by setting the zero-point first and then the span-point (refer to Table 5-7).
The software allows this adjustment to be made in 100, 10 or 1 count increments.
