Now the analog output channels should either be automatically calibrated or they should be set to manual calibration, which is described next.

6.13.4.3. Manual Analog Output Calibration and Voltage Adjustment

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 6-15). Adjustments are made using the touchscreen buttons by setting the zero-point first and then the span- point (Table 6-20).

The software allows this adjustment to be made in 100, 10 or 1 count increments.
