BENCH MODEL MULTIMETER
Ohm/Continuity/DIODE
The Meter is capable of measuring Ohm up to 220MΩ.
To perform a measurement:
1. Turn rotary switch to Ωposition
，
LCD panel displays‘Ω’; press FUNC button to select continuity function or
diode function;
2. Connect red test lead with VΩHz terminal and black test lead with COM terminal;
3. Press FUNC button selecting a function of the ohm
、
continuity or diode
。
4. Connect test leads to test circuit;
5. The function and measurement are displayed;
6. The beeper emits a continuous tone if the input is approximately below 30Ω.Under diode test,The forward voltage
of the semiconductor junction is measured.
Note: In case of performing resistance or continuity test on circuit board, it is necessary firstly to turn off the power of
the circuit board and then perform the measurement. As there may be other parallel circuits, so the displayed
value of test is not surely the actual value of the resistance.
