LAUNCH
Multimeter is mainly used to test voltage, current, resistance, diode and Make-and-break. The unit will
determine if the device is operating normally, a fault is detected and if the circuit is complete.

4.1 Operations

1. First connect the EM101N to power supply.
2. Connection method varies with tested object. Please refer to the following method to test:

4.1.1 Voltage Measurement

DC voltage and AC voltage measurement apply the same connection method.
1. Tap Toolbox -> Multimeter on the diagnostic tool to enter the following screen.
2. Select DC voltage/AC voltage and corresponding range. Tap Not connected to search for EM101N.
When it is successfully connected, the diagnostic tool will display connection status.
3. Insert one end of black test pen into COM terminal of EM101N, insert one end of red test pen into V/Ω
terminal of EM101N.
4. Attach black and red test pen tip to tested point. Keep test pen attached to it firmly.
