Description
【Test Applications】With the BT250 power circuit probe tester, you can test for voltage and polarity/continuity/signal circuits/bad ground contacts/short and open circuits. And most importantly, you can also use it to check the on/off of switches, relays and diodes, fuses and circuits, activating electronic components in your hands/in your vehicle/with a ground. It is the best electrical tester to reduce the diagnostic time of all 6-30 volt vehicle electrical systems..【4 Adjustable Modes Circuit Tester】AC detects the maximum and minimum voltage, supply frequency and duty cycle of the circuit under test; DC detects the voltage value of the circuit under test. In addition,the circuit tester can also detects the resistance between the circuit probe under test and the auxiliary ground; Diode Test can quickly test the operation of the diode assembly and determines if it is conducting. The last mode is the audio tone mode..【Wide Vehicles Application】 Electrical tester can support 6-30V cars, boats, trailers, ATV, motor homes and many other vehicles. With the ability to power components such as radiator fans, starter motors, relays, window regulators, windshield wipers, etc. Powered by the car battery or cigarette lighter, no extra battery or cable required..【LED Indicator & Easy to Operate】Power circuit probe tester built-in LED light allow you to work in the dark area, there will be beep tone when detecting,operate the tool without looking at the menu once you are familiar with the tone.Provide 4.9ft of electrical wire for easy use..【Circuit Overload Protection】The BT250 automotive circuit tester provides more safety for the user because it is protected by the inner circuit breaker. If overloaded, it will trip and automatically disconnect the protection circuit. The circuit breaker is a valuable test tool as well as a safety measure to protect the tool from overload and make the product more durable.
