12. Switch the range calibrator RANGE to 300 µW.
13. Record the DVM voltage reading as value B in the test record.
14. Wait for the power meter reading to settle (no settling drift within 20 seconds).
15. Record the power meter reading as value C in the test record.
16. Switch the range calibrator RANGE to 100 µW.
17. Record the DVM voltage reading as value D in the test record.
18. Wait for the power meter reading to settle (no settling drift within 20 seconds).
19. Record the power meter reading as value E in the test record.
20. If testing a dual-channel power meter, perform steps 7 through 19 for the other
channel.
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.
