lists the equipment required for the performance tests.
Before you do the performance test, make sure to warm up the calibrator.
To test each function and operating ranges:
1. For each step in
, set the DUT to the specified function and range.
2. Connect the source to the input jacks on the DUT.
3. Apply the output from the source. For temperature connections, see
4. Make sure the DUT readings are within the limits in
.
