will display some information. In this situation, press short circuit “V
－
”
and “COM” terminal to reset the meter to zero.
◼
Within the AC voltage function, press the key "Select" to measure the
frequency of the AC voltage source.
◼
The value of the AC voltage measured with this meter is True RMS (root
mean square). These measurements are accurate for sine wave and
other waves (without DC offset), square wave, triangular wave and step
wave.
3.2.2 Frequency measurement
To avoid any electric shock and/or damage to the meter, do
not attempt a frequency measurement if the voltage is over
750V for DC current or AC current(valid value).
Frequency measurement at the Hz
%
position:
◼
Turn the rotary switch to the position Hz%.
◼
Connect the test leads in black and in red to COM input socket and Hz
input socket respectively.
◼
Use another two ends of the test lead to measure the frequency of the
circuit to be measured.
◼
Read the measured frequency on LCD screen.
Frequency measurement at the ACV position:
(
It is only applicable to
measuring frequencies less than 1KHz.
)
◼
Turn the rotary switch to the position
～
6V/60V/600V/750V.
◼
Press the "Select" key to select "Hz".
◼
Connect the test lead in black and test lead in red to COM input socket
and V input socket respectively.
◼
Use another two ends of the test lead to measure the frequency of the
circuit to be measured.
◼
Read the measured frequency value on LCD screen.
