The setup in Figure 3 measures the 200 μA, 2 mA, 20 mA, and 200 mA current ranges of
channel 1. The setup in Figure 4 measures the 1 A current range of channel 0 and the 2 A current
range of channel 1.

and 200 mA Current Ranges of Channel 1

Channel 0 and the 2 A Range of Channel 1
Table 7 lists the test points you must request from the NI 4130 in DC Voltage mode and measure
with the DMM to complete verification. For each iteration, set the current limit of the NI 4130
to the value in the Output column of Table 7.
To ensure the system has had adequate time to settle, wait one second after requesting a new
current limit before taking a measurement with the DMM.
When applicable, configure the Fluke 5700/5720A/5730A calibrator to the Resistance value for
the corresponding channel and range in Table 4. Enable external sense (4-wire mode) on the
NI 4130 Fluke 5700A/5720A/5730A
