6.7.3.5. Manually 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 (see Figure 6-2). Adjustments are made
using the front panel keys. First the zero -point is set then the span-point
(Table 6-12).
The software allows this adjustment to be made in 100, 10 or 1 count increments.
