Power Meter Accuracy Test
1. General Information
Step 17. Record the DVM voltage reading as value D in the test record.
Step 18. Wait for the power meter reading to settle (no settling drift within 20 seconds).
Step 19. Record the power meter reading as value E in the test record.
Step 20. If testing a dual-channel power meter, perform Step 7 through Step 19 for the other
channel.
Step 21. Perform the pass/fail calculations indicated on the test record.
NOTE If a channel of the power meter does not pass this test, the power meter cannot be used in
applications that require Option G12 or H12. There are no adjustments that can be
performed to improve the performance of the power meter. Typically, replacing the A6
measurement assembly associated with the failed channel will correct the problem.
