6.5.2 Unipolar Calibration(Only for ACL-8112DG/HG)
1. Adjust the voltage calibrator’s voltage output to –4.9987V . Connect
the voltage calibrator’s <+> to CN3.AI0 <PIN 1> and the voltage
calibrator’s<-> to CN3.AGND<PIN 9>.
2. Trim VR2 to obtain a reading that toggles between 0 and 1. This
value is displayed on the monitor of the calibration program
8112UTIL.exe. Then proceed to the next step.
3. Adjust the voltage calibrator’s voltage output to +1.22mV . Connect the
voltage calibrator’s <+> to CN3.AI0 <PIN 1> and the voltage
calibrator’s<-> to CN3.AGND<PIN 9>.
4. Trim VR6 to obtain a reading that toggles between 0 and 1. This
value is displayed on the monitor of the calibration program
8112UTIL.exe. Then proceed to the next step
5. Adjust the voltage calibrator’s voltage output to +9.9963V . Connect
the voltage calibrator’s <+> to CN3.AI0 <PIN 1> and the voltage
calibrator’s<-> to CN3.AGND<PIN 9>
6. Trim VR1 to obtain a reading that toggles between 4094 and 4095.
This value is displayed on the monitor of th e calibration program
8112UTIL.exe.
A calibration utility software diskette is included in the product package.
Detail calibration procedures and description can be found in the utility.
Users need to execute the calibration utility and follow the procedures
carefully to obtain best results and accurate measurements.
