1. Keep your clothing, hair, hands, tools, and test equipment at a safe distance from all operating or hot equipment to prevent accidents.
2. Take special care when working near the ignition coil, distributor cap, ignition wires, and spark plugs—these components can unleash dangerously high voltages when the engine is running.
3. Always have a fire extinguisher readily available when dealing with gasoline, chemicals, or electrical equipment to swiftly tackle any potential fire hazards.
4. Before beginning any tests, make sure to securely place the transmission in Park (for automatic vehicles) or Neutral (for manual vehicles) and engage the handbrake.
6. For your safety, avoid connecting or disconnecting any test equipment while the ignition is on or the engine is running. Your attention to these safety measures will ensure a secure and efficient testing experience.Online Support>>

This circuit tester is incredibly convenient to use! The multimeter mode is extremely useful, handling DC voltage, diode, and resistance tests all at once, while the oscilloscope mode provides a very stable display.
What I like most is its component activation function and 0–5V adjustable voltage output. The interface is simple, and operation is effortless. I’m very satisfied with the results after using it for a few weeks.

It’s worth mentioning that the first one I bought had a problem with another buyer, but I liked the software, so I decided to buy it here, and it’s definitely a wonderful product.

I absolutely love this tool! The flashlight design solves the problem of use in dark environments, and the multiple working modes are compatible with different appliance models. The multimeter can test DC voltage/resistance, and the oscilloscope can display waveforms. Two-year warranty, highly recommended!

This MRCARTOOL circuit tester is a fantastic product—its flashlight function is perfect! It has multiple modes (DC voltage, resistance, oscilloscope) and an adjustable output voltage of 0-5V, which is sufficient for all my automotive circuit tests. I especially like its multilingual support and two-year warranty. Customer service also responded quickly. Highly recommended!

Many of my customers purchase this product at our small shop. Though it’s a small item, it makes a big difference. My clients say it helps them troubleshoot car battery issues on their own, saving them a lot of time and repair cost
