3.4MANUALLY CALIBRATING ANALOG OUTPUT SIGNAL LEVELS

The analog outputs in voltage mode can be manually calibrated to closely match the characteristics of the data recorder. Outputs configured for 0.1V full scale should always be calibrated manually.

Calibration is done through the instrument software in conjunction with a voltmeter connected across the output terminals. Adjustments are made using the front panel keys. First the zero-point is set then the span-point.

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

Full Scale	Adjust Zero Within	Span Voltage	Adjust Span Within
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
