## Description

P200 Power Circuit Probe Kit - Advanced Automotive Electrical System Multimeter, Oscilloscope, Automotive Circuit Tester, Fuel Injector Activator, Short Circuit Finder - 9~30V

## Features

- [P200 Automotive Diagnostic Scanner] Topdiag P200 car scanner can be used to test voltage, fuel injector, diode, continuity, polarity, etc, which is the only upgradeable automotive 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 basic functions of P200 car diagnostic scanner-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 scan tool 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 diagnostic scanner 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 car scanner diagnostic 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 car scan tool'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 as a digital circuit breaker finder, its internal circuit breaker will open circuit or trip automatically if it becomes overloaded.
- [Multiple Languages & Online Upgrade Available] Our automotive scanner diagnostic tool supports 18 languages and online upgrade. When you need to upgrade,connect the device to the computer and after the upgrade software is opened, long press the "left" key and "OK" key at the same time. The computer can detect the device memory card, then click the software and follow the steps to upgrade.

## Questions & Answers

**Q: What does the product include?**
A: Hi, the product includes a Topdiag P200, 2 battery clips, 3 probes, an user’s manual and 20ft extension cable.

**Q: How does it find a short circuit?**
A: Thanks for the inquiry, if you are tracing a short circuit in the brake light circuit, you will know that the wiring harness must pass through the wire at the door sill, locate the color-coded wire in the harness and expose it. While in Component Activation interface, select MOMENT mode. Use the probe tip to contact the marked wire. Press the "UP" button to trigger power supply.
If the circuit breaker tripped, you have verified the shorted wire. Cut the wire and power supply each end with probe tip again, follow the wire in the shorted direction and repeat this process until the short is located.

**Q: Can the house current be tested?**
A: Thanks for your inquiry, P200 is an electrical circuit tester which tests cars, minibus, SUV, pickup truck, motorcycle, Jeep, etc, can not be used to test the current in the house.

**Q: How to test trailer lights?**
A: Hi, thanks for your question! When the probe is in multimeter or SMART Test , connect the probe auxiliary ground lead to the trailer light, and insert the probe tip into the OBD socket to display the current voltage. With this method you can check the function and direction of the connector and trailer lights. If you find the trailer light connection correctly, you can use the "Component Activation" function to test whether the trailer light is working or not working.
