2.
Set the DMM measurement range to
10 V
.
3.
Measure the analog output voltage on each channel by calling
nirio78xxCalibrationSetAOVoltage.vi
.
4.
Compare the resulting value shown by the DMM to the 1-year limits in the appropriate
Analog Output Accuracy Verification Test Limits
table in the
Test Limits
section of this
document. If the value is within these limits, the device passes the test.
5.
Repeat steps 3 through 4 for each test point in the following
Analog Output Accuracy
Verification Test Limits
table.
6.
Disconnect the DMM from the NI R Series device.
7.
Repeat steps 1 through 6 for all AO channels on the device.
