4.8.4.3. 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 (refer to Figure 4-24). Adjustments are made using the control
buttons by setting the zero-point first and then the span-point (refer to Table 4-12).
The software allows this adjustment to be made in 100, 10 or 1 count increments.
Table 4-12: 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
IMPORTANT
Outputs configured for 0.1V full scale should always be calibrated manually.
