Feature
●【Electrical Tester with 4 Working Modes】DC Voltage: The power circuit probe tester will read DC voltage with 0.1 volt resolution. AC Voltage: The LCD display of the circuit tester will read the maximum and minimum voltage, frequency and duty cycle. Resistance: The tester will read the resistance between the tip and the auxiliary ground lead. Diode Mode: quickly test the operation of the diode assembly and determine if it is conducting.
●【Self-test & Circuit Breaker Protection & 7 Languages】Before using the automotive circuit tester, the quick self-check function of the tester can ensure that the tester is in good condition. The tool is short circuit protected and its internal circuit breaker will trip if overloaded. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from Overload. The automotive tool supports 7 languages: English, German, Spanish, French, Italian, Russian, Portuguese.
●【Portable and Quick Test Circuit Tester】With this car circuit tester tool, you can determine at a glance whether a circuit is positive, negative, or open without having to reconnect the clips from one battery pole to another; Test for continuity with its built-in auxiliary ground lead; Test for poor ground contacts instantly without performing voltage drop tests; Follow and locate short circuits without wasting fuses.
●【POWER SUPPLY】The automotive power circuit probe tester is powered via the vehicle battery. Connect the RED battery clamp to the POSITIVE terminal of the vehicle’s battery, and the BLACK clamp to the NEGATIVE terminal. When the power circuit probe tester is first connected to a battery (power source), the car electrical tester will sound a beep and the headlights will be on to illuminate the test area of the probe tip.
●【Easy-to-Operate Exhaust Back Pressure Gauge】The exhaust pressure tester is tested at idle and 2500rpm. The pressure should be lower than 1.25psi at idle, and lower than 3psi at 2500rpms. The tester has a 2.5-inch gauge, 2 pressure units (PSI and bar), and 3 colors to indicate good or bad status. The highly visible mark greatly helps users to directly read the data.
