5. To test the capacitance gain:
(1) Make sure you have carefully read the “Test Conditions”.
(2) Switch to Capacitance measurement and select a range listed in the table
below.
(3) Connect one end of a shielded cable to the input terminal of the meter and
leave the other end free, then enable the REL operation.
(4) Connect the other end to the calibrator.
(5) Input signals in accordance with the table below using the calibrator and
compare the results with the limits from the table (make sure the calibrator
can adequately output).
(6) Repeat step 2, 3, 4 and 5 to finish the test.
