d)
Start the task.
e)
Read the samples from the NI 9202.
f)
Average the samples.
g)
Clear the task.
6.
Compare the averaged samples to the limits in the
NI 9202 Verification Test Limits
table
to verify the input accuracy. If the values are within these limits, the device passes the
test.
7.
Set the calibrator to Standby mode (STBY).
8.
Repeat steps 3 through 7 for each test point in the
NI 9202 Verification Test Limits
table.
9.
Disconnect the calibrator from the device.
