properly.
Verification
This section provides instructions for verifying the NI 9219 specifications. The following
performance verification procedures describe the sequence of operation and test points required
to verify the NI 9219 and assumes that adequate traceable uncertainties are available for the
calibration references.
Caution
The analog inputs on the NI 9219 are not grounded (floating). Ensure that
a single point in the test system is connected to ground to prevent the entire system
from floating.
Voltage Accuracy Verification
Complete the following steps to verify the voltage accuracy of an NI 9219.
1.
Connect the NI 9219 to the DMM and source as shown in Figure 1.
