III.2.1. True RMS value of AC Voltage
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 to the circuit to be measured.
c. Read the measured RMS value from the LCD display.
III.2.2. HOLD, MAX, MIN and PEAK value of AC Voltage
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 to the circuit to be measured.
c. The measured value is displayed in the LCD display. If the
▼
button is
pressed, the symbol of “HOLD”, “MAX”, “MIN” or “PEAK” will be shown in
LCD alternatively. And the value of the HOLD, MAX, MIN or PEAK
function will be displayed in LCD alternatively.
d. To return to the display of current measurement, hold the
▼
button for
more than 2 seconds.
NOTE: NOTE: The PEAK function displays the maximum value of a AC periodic
waveform. The sampling time for the PEAK function is 39 μs (50Hz) or 33μs (60Hz).
The HOLD, MAX, or MIN function displays the true RMS value.
