24. Call the niDMM Cal Adjust Gain VI with the following parameters:
25. Connect the NI 4071 and the Fluke 5720A calibrator using the Fluke 5440 cable, as shown
in Figure 6. Table 15 lists the cable connections.
26. Wait two minutes for the thermal EMF to stabilize.
27. Generate 10 mA on the calibrator with the current output set to
NORM
.
28. Call the niDMM Cal Adjust Gain VI with the following parameters:
29. Generate –10 mA on the calibrator with the current output set to
NORM
.
