【Powerful Circuit Tester Kit】The P200 Automotive Circuit Tester is the only circuit tester on the market that can be upgraded, a tool for quickly testing all ✅9V-30V✅ electronic systems. It can diagnose problems in the components, electrical circuit systems or fuel injectors of the car in the shortest time. Not only the test time is greatly shortened, but also more intelligent and intuitive, suitable for any novice driver or maintenance engineer..
【Fuel Injector & Relay Tester】It is extremely important to regularly test the fuel injector. Damage to the fuel injector can easily lead to unstable idle speed of the engine, increased fuel consumption, causing engine shock. It is worth mentioning that TopDiag P200 auto circuit tester has been added 300+ USD valued powerful functions, namely: ✅Fuel Injector Test✅ Relay test mode. TopDiag makes diagnosing your car easier and saves maintenance costs..
【0~5V Adjustable Power Supply & Activating Components】0~5V power is useful when checking the wiring to the ECU/ECM, also meet the voltage requirements for the sensitive parts with low voltage. Besides positive activation, negative activation is our n....

Dynamic phase loss, static phase loss protection: refers to the phase failure of any phase when the protected device is in the running state or non-operating state. The indicator light is in the form of red light and priority.
Wrong phase protection: A protection measure to prevent the phase sequence of L1, L2, L3 three-phase AC power supply from being connected incorrectly. Instant action. The indicator light is in the form of yellow light..
Voltage Unbalance Protection: Refers to a voltage imbalance that will affect the safe operation of the device. When the voltage imbalance rate is higher than 8%. The form of the indicator light is: the lack of phase red light is on, and priority..
Delay protection: When there is a fault, the monitor will delay after 1~2 seconds, and the relay will release..
The protection function of the monitor is not affected by the current of the line or load, the inrush current, the unbalanced current and the nature of the load. Long-term work with full performance and full climate. Power consumption is no more than 2W..
