8.2 Analog Input Resistance Calibration
Model: ADAM-4013
1. Apply power to the module and let it warm up for about 30 minutes.
2. Assure that the module is correctly installed and is properly
configured for the input range that you want to calibrate. You can do
this by using the ADAM utility software. (Please refer to Appendix
D, Utility Software.)
3. Apply the reference Span resistance to the screw terminals using a
4-wire connection. Please refer to Figure 8-5 for the correct wiring
diagram and Table 8-2 for the right Span calibration resistance).
Figure 8-5 Applying calibration resistance
Use a precision resistance decade box or discrete resistors with values:
10 W, 15 W, 60 W, 140 W, 200 W and 440 W.
4. Apply the reference Offset resistance to the terminals of the module.
(Please refer to Figure 8-5 for the correct wiring diagram and Table
8-2 for the right Offset calibration resistance.)
5. Issue an Offset Calibration command to the module. This can be
done by using the Calibrate option in the ADAM utility software
(Please see Appendix D, Utility Software)
6. Issue a Span Calibration command to the module. This can be done
through the Calibrate option in the ADAM utility software (Please
see Appendix D, Utility Software)
