This unit is a electrical tester for reducing diagnosstic time in automotive electrical system. After a simple hook up of the unit to the vehicles battery, automotive techinician can conduct a positive or negative battery current to the tip by roking the rock switch forward or backward.
Can be used to test continuity, test polarity of a voltage, check lamp, check electric motor, follow and locate short circuits, test for bad ground contacts and measure dc voltage from 2V to 24V etc.
Long test lead. The cable length is about 5m which allows you test any electrical system easily.
Easy to use. Powered by the vehicle battery directly. The illumination function enables automotive technician to test the electrical system in the darkness.
Take the insufficient light environment in consider, the tool built in flashlight to indicate the DC voltage measurement.
Safety insurance. When the current exceeds 8A, the unit will disconnect the current automatically.
