Diode Measurement - Launch EM101N User Manual

LAUNCH
2. Select Resistance, tap Not connected to search for EM101N. When it is successfully connected, the
diagnostic tool will display connection status.
3. Insert black test pen into COM terminal of EM101N, insert red test pen into V/Ω terminal of EM101N.
4. Attach black and red test pen to metal part of resistance ends. Keep test pen firmly attached to
resistance.
5. Numerical value will be displayed directly on the diagnostic tool.
Note: You can touch resistance with hands during measurement, but do not touch both ends of resistance
simultaneously, as it will affect measurement accuracy.

4.1.4 Diode Measurement

This EM101N can measure light-emitting diode and rectifier diode. The way test pen is placed is the
same with voltage measurement.
1. Tap Toolbox -> Multimeter on the diagnostic tool to enter.
2. Select Diode, tap Not connected to search for EM101N. When it is successfully connected, the
diagnostic tool will display connection status.
