1. Intelligent test. No need to select the mode after startup, can quickly detect the voltage, resistance, diode in the vehicle electrical system line.

2. Can be used to activate and start fuel pump, solenoid, blower, cooling fan, headlights and other components

3. Flexible testing. Flexible test voltage, frequency, duty cycle, fuel injection nozzle, automatic drawing waveform signal, simple switching, convenient operation.

4. Continuity detection. Continuity testing can quickly detect whether a car circuit system is on or off.
