● Press【V 】and it will be in DC voltage
measurement .
● There are 3 measurement modes: DCV，DCV＋ACV
and dBm. Press【SELECT】to select one of them.
● When the power is on, the measurement will be on AUTO state. Press【RANGE】
to select range manually: 8.0000V/80.000V/600.00V
● According with the user’s requirements, press（【REL】 【MAX/MIN】 and
【2nd VIEW】）to do test and record. All of them will be on slave display.
● Insert the red test leads into “VΩHz” terminal and the black test lead into “COM”
terminal. Contact the test points with the test leads. Please refer to Chart 5. The
measured value and relative symbols will be on master and slave screen at the
same time. Please refer to Table 5:

dBm dBm Hz/DCV/ACV/DCV+ACV
● In dBm test，the default impedance is 600Ω. Press【RANGE】to change the load
impedance and the selectable values are as below: 4Ω, 8Ω, 16Ω, 32Ω, 50Ω, 75Ω,
93Ω, 110Ω, 125Ω, 135Ω, 150Ω, 200Ω, 250Ω, 300Ω, 500Ω, 600Ω, 800Ω, 900Ω,
1000Ω and 1200Ω. In dBm measurement mode, the decimal point of dBm is
fixed between the second and third digits and 【REL】, 【MAX/MIN】and 【P-H】
are disabled.
5.2 AC Voltage measurement
Warning: The measured voltage must not exceed AC 450V because the high
voltage standard of this DMM is IEC 61010 CAT II 600V！
Note: Before tests on low voltage, please connect the test leads in
short-circuit and press【REL】to make zero for a better accuracy!
● Press【V 】 to enter AC voltage function
● AC voltage has three states of ACV，ACV＋Hz
and dBm. Press【SELECT】 to choose one of them.
When the power is on, the measurement is
in AUTO state. Press【RANGE】 to select
suitable range. The selectable ranges are as
below: 8.0000V/80.000V/450.00V
● Press (【REL】,【MAX/MIN】 and
【2nd VIEW】）to do relative test and
record. All of them can be on slave
