Kkmoon Car Circuit Tester Multi Function DC5‑30V Digital Real Time Display Electrical Voltage Test Pen for Vehicles

Feature: 1. Multi Function: The car test pen integrates the functions of voltage measurement, bulb load measurement, voltage measurement with bulb load, test at the load of electrical appliances, and power supply polarity display. 2. Voltage Measurement Function: The voltage measurement function of the car tester pen is the same as the voltage measurement of the multimeter, the operation is not difficult. 3. Bulb Load Measurement: Using a 5W car bulb as the load, the brightness of the bulb can quickly determine the line power supply failure. Compared with the diode test pen, it can show hidden faults such as poor circuit contact and excessive resistance. 4. Voltage Measurement with Bulb Load: By measuring the brightness of the light bulb of
