Verifying Voltage Programming Accuracy
To verify the voltage programming accuracy, compare a set of requested voltage test points to
measurements of the actual voltage by the DMM. Refer to the following figure for the necessary
connections.
Figure 1. Voltage Accuracy Verification and Adjustment Setup for the NI 4130
Table 5 lists the voltage test points for each channel that you must request from the NI 4130 and
measure with the DMM to complete verification. Take voltage measurements using the DMM
at each test point, and compare the result to the programmed voltage value from the Output
column of Table 5 to calculate the output error. Compare the output error to the Test Limit for
the iteration of channel x in Table 5. If the output error is outside the test limit, adjust the
NI 4130.
To ensure that the system has had adequate time to settle, wait one second after requesting a new
voltage before taking a measurement with the DMM.
When you have verified all iterations per channel, this part of the verification is complete.
