## Description

Topdiag P200 Power Circuit Probe Kit - Test Light Automotive Circuit Tester Circuit Breaker Finder Tool, Relay Tester Multimeter, Oscilloscope, Fuel Injector Tester - 9~30V: desertcart.com: Tools & Home Improvement

## Features

- [P200 Power Circuit Probe Tool] Topdiag P200 probe tester can be used to test voltage, fuel injector, diode, continuity, polarity, etc, which is the only upgradeable power circuit tester on the market. It is a tool for quickly testing all 9V-30V electronic systems. The test time is greatly shortened, convenient, fast and intelligent!
- [Multimeter & Oscilloscope Mode] There are two powerful functions of P200 power circuit probe kit - one is the multimeter mode, which can quickly test DC voltage, resistance, continuity, diode, current and frequency; the other function is oscilloscope, which can quickly analyzes and diagnoses the problems of vehicles by display electrical waveforms on the screen.
- [Fuel Injector Testing] If the fuel injector is damaged, that will easily lead to engine idling instability, fuel consumption increase, cause engine shock. Also, Topdiag P200 power tester also a relay tester automotive kit, which will make it more convenient for the owner to check whether the fuel injector and other parts of the vehicle in a good condition regularly.
- [Component Activation Function] P200 circuit tester can activating components of vehicles, which is used to generate activation signals to the detected components, such as activating lights. There are two activation methods, positive activation and negative activation. The maximum current through activation can reach 20A, There are the three activation modes: MOMENT, LACH and PULSE.
- [0~5V Adjustable Power Supply] Togdiag P200 is a power circuit probe test kit for all cars, so it can adjust 0~5V output voltage to check the circuit connection and it is also useful to check the wiring to the ECU/ ECM, which can ensure the safety of the tested vehicles.
- [Positive & Negative Test] Use the P200 electric tester's probe to find the positive and negative of the power supply. If it is positive,the screen will display the probe voltage and the buzzer will alarm. If it is negative, the grounding icon is displayed on the screen.
- [Circuit Breaker & Overloaded Protection] With the function of automatic short-circuit protection and overloaded protection, you can think of the Topdiag P200 test probe as a digital circuit breaker finder, its internal circuit breaker will open circuit or trip automatically if it becomes overloaded.
- [Multiple Languages & Wide Application] Our P200 automotive power circuit probe tester support 18+ languages, such as English, Spanish, German, Polish, Russian, Vietnamese, Arabic, Italian, Portuguese, French, Korean, Japanese, Indonesian and Chinese, etc. Topdiag P200 electrical tester is compatible with all 9V-30V vehicle electrical systems - cars, excavators, trucks, boats and motorcycles, etc. If you have any suggestions or problems with our products, please feel free to let us know.
