6.6.2.2. Manual Analog Output Calibration and Voltage
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 6-5). Adjustments are made using
the front panel keys by setting the zero-point first and then the span-point (Table
6-12).
To select manual output calibration for a particular channel, activate the ANALOG
I/O CONFIGURATION MENU, then press:

Now the analog output channels should either be automatically calibrated or they
should be set to manual calibration, which is described next.
The software allows this adjustment to be made in 100, 10 or 1 count increments.
