allsun Digital Automotive Electrical Circuit Tester 2-24V DC Pen Type Vehicle Diagnostic Tool Auto Electrical System Diagnosis Test Device

Description

INTRODUCTION This circuit tester is the best car electrical tester for reducing diagnostic time in automotive electrical systems. After a simple hook-up of it to the vehicle's battery, the automotive technician can conduct a positive or negative battery current to the tip by rocking the rock switch forward or backward. This circuit tester can be used to measure dc voltage and test for continuity or for bad ground contacts, It can also be used to follow and locate short circuits. FEATURES Overload Protection: The circuit tester is equipped with a built-in circuit breaker for overload protection. After the circuit breaker trips, it will be reset automatically. Illumination: Taking the insufficient light environment into consideration, the electrical tester kit built-in flashlight to indicate the DC voltage measurement. No Extra Battery Needed: The circuit tester is powered by the 12V vehicle battery directly. APPLICATIONS Using Illumination Measuring DC Voltage Polarity Test Continuity Test Activating Components out of the Vehicle's Electrical System Testing Trailer Lamps and Connections Activating Electrical Components Jumper Lead Feature.
