III.2.6. Crest Factor (C.F.)
a. Set the rotary switch at position V. Then select the correct fundamental
frequency by moving the sliding switch at the side of the tester.
b. Insert the test leads into the input jack. Connect the test prods of the test
leads in PARALLEL with the circuit to be measured.
c. Press the FUNC button four times. The symbol of C.F. will be shown in
LCD. The crest factor (C.F.) will be measured and displayed. The crest
factor (CF) is defined as following:
C.F. (Crest Factor) = (Peak Value) / (RMS Value)
III.2.7 Frequency of AC voltage
a. Set the rotary switch at position V.
b. Insert the test leads into the input jack. Connect the test prods of the test
leads in PARALLEL with the circuit to be measured.
c. Press the FUNC button five times. The symbol of Hz will be shown in
LCD.
d. The frequency of AC voltage will be measured and shown in LCD. If the
frequency is less than 40 Hz, 0 Hz will be shown in LCD. If the frequency
is greater than 65 Hz, OL Hz will be shown in LCD
NOTE: The AC voltage must be greater than 50V for frequency measurement.
