ELECTRICAL ANALYSIS
● When measuring the peak voltage, con-
nect the peak voltage adaptor to the digi-
tal tester and switch the selector to the
DC voltage mode.
NOTE:
● Make sure the adaptor leads are properly
installed in the digital circuit tester.
● Make sure the positive pin (the “+” mark
facing up as shown) on the adaptor is
installed into the positive terminal of the
tester.
● The test harness is needed for the follow-
ing tests.
