Now the analog output channels should either be automatically calibrated or they should
be set to manual calibration, which is described next.
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 (Figure 4-4). Adjustments are made using the front panel buttons by
setting the zero-point first and then the span-point (Table 4-13).
The software allows this adjustment to be made in 100, 10 or 1 count increments.
