6.
Verify that the recorded value falls within the test limits.
7.
If more than one limit range is specified, repeat the previous steps using the values
specified in each limit range.
8.
If more than one level range is specified, repeat the previous steps using the values
specified in each level range.
Verifying Load Regulation
Note
Although load regulation is listed as a typical specification for the
PXIe-4135, verification is required to ensure the procedures listed for verifying other
specifications are correct. If the PXIe-4135 fails the load regulation verification
procedure, discontinue use of the device and contact an authorized NI service
representative to request a Return Material Authorization (RMA).
Refer to the following table as you complete the following steps:
Table 7. Load Regulation Verification
