MS8218 True RMS Multimeter
Operation Methods
Logic Frequency/Duty Ratio Measuremeat
The testing chart is shown in the Figure 3-4.The frequency range is of 5Hz
～
2MHz
（
Vp 2.5
～
5V
）
,while the duty ratio
measurement range being of 5%
～
95%.And the measurement methods are as follows:
1.
Turn on the power switch and set the rotary switch to the position
%
.
2.
Insert the red testing line into the
V
Ω
Ω
Ω
Ω
Hz
end and the black testing line into the
COM
end.
3.
Press the
SELECT
key to select the logic frequency(Hz) or duty ratio( ) modes.
4.
Connect the red testing line to high logic level, the black one to low logic level.
5.
Read the measured value from the display screen. If the frequency of the measured signal is lower or higher than the
meter’s measurement range, the reading will be displayed as zero. If the amplitude of signal is too low or the low level
is larger than 1 volt, the reading will also displayed as zero.
6.
This measurement is of automatic range, it is null to press the
RANGE
key.
