Verifying DC Accuracy
This procedure verifies the DC accuracy of the PXIe-5113 by comparing the voltage measured
by the device to the value sourced by the voltage standard.
Caution
Avoid touching the connections when generating a high voltage from the
calibrator.
Refer to the following table as you complete the following steps.
