NOTE: a
：
At 200Ω range, it should make the test leads short to measure the
wire resistance, then, subtracts from the real measurement.
b
：
At 200 MΩ range, make the test leads short, LCD displays 1.0MΩ, it’s
normal and has no effect on the accuracy and should be subtracted from
real measurement.

DCV MEASUREMENT
1
．
Apply the black test lead to “COM” terminal and the red one to V/Ω/Hz
terminal.
2
．
Set the knob to a
proper DCV range, connect the black test lead crossly to the circuit under
tested, the voltage and polarity of the point which the red lead connect to
will display on LCD.
NOTE:
1
．
If the voltage range is unknown beforehand, set the knob to the highest
range, then, select a proper range according to the displaying value.
2
．
There is a remained value at small voltage range before measuring, it is
normal and have no effect on measurement. If MSD displays “1”, it means
over range, should set the knob to a higher range.
3
．
Do not input a voltage over 1000V, or, the circuit might be damaged.
4
．
Be careful when measuring high voltage circuit.
4-3
．
ACV MEASUREMENT
1
．
Apply the black test lead to “COM” terminal and the red one to V/Ω/Hz
terminal.
2
．
Set the knob to proper ACV range, connect the test leads crossly to the
circuit under tested.
NOTE:
1
．
If the voltage under tested is unknown beforehand, set the knob to the
highest range, then, select a proper range according to the displaying value.
2
．
There is a remained value at small voltage range before measuring, it is
normal and have no effect on measurement. If MSD displays “1” , it means
over range, should set the knob to a higher range.
3
．
Do not input voltage over 750Vrms
，
or, the circuit might be damaged.
