To select manual output calibration for a particular channel, activate the ANALOG I/O
CONFIGURATION MENU (see Section 4.6.3), then press:

Now the analog output channels should either be automatically calibrated or they should
be set to manual calibration, which is described next.
4.6.3.3. 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 4-4). Adjustments are made using the front panel buttons by
setting the zero-point first and then the s
pan-point (Table 4-13).
The software allows this adjustment to b
e made in 100, 10 or 1 count increments.
Table 4-13. Voltage Tolerances for Analog Output Calibration
Full Scale Zero Tolerance Span Voltage Span Tolerance
0.1 VDC ±0.0005V 90 mV ±0.001V
1 VDC ±0.001V 900 mV ±0.001V
5 VDC ±0.002V 4500 mV ±0.003V
10 VDC ±0.004V 4500 mV ±0.006V
NOTE
Outputs configured for 0.1V full scale should always be calibrated manually.
