Adjusting 2-Wire Resistance
To adjust 2-wire resistance for the NI 4065, complete the following steps:
1.
Connect the NI 4065 and the Fluke 5700A/5720A calibrator using
two sets of Fluke 5440 cables, a double banana plug, and
two insulated, low EMF spade lugs, as shown in Figure 5. Table 9 lists
the cable connections.
2.
Wait two minutes for the thermal EMF to stabilize.
3.
Call the niDMM Config Measurement VI. The niDMM Config
Measurement VI is polymorphic. To change the selected instance of
this polymorphic VI, right-click the VI and choose
Select Type
followed by
Resolution in Digits
.
4.
Call the niDMM Control VI.
5.
Output 100 M
from the calibrator with 2-wire compensation and
external sense turned off.
Allow the calibrator output to settle before
proceeding
