Why is the volume still low when I turn the signal up to the highest level? What Can I do?

1. When the signal is not strong enough, the volume will be low, please find a strong signal and try it out; 2. The battery power supply is insufficient, please replace the battery and try again. If the issue still occurs, please reach us directly.

Can this tester accurately locate the short circuit point?

Sorry, it can’t, only for the short area. We recommend that you use a more professional short circuit test instrument, such as a short circuit tester equipped with a needle meter so that you can find the short circuit point more accurately.

Why V210 can’t locate the short point accurately?

V210 is an entry-level tester and can only roughly determine the short circuit area but also the short point. When testing multiple and complex wires, locating the short circuit point based on sound is easily affected by other lines.

Must-Have Diagnostic Tool

If you're dealing with electrical gremlins in cars, motorcycles, trailers, or even lawn equipment, the VDIAGTOOL V210 is absolutely essential. I used it to track down an open wire in a tail light circuit that would have taken me all day using a multimeter alone. With this tool i found it in under 10 minutes.Fast & Accurate:It instantly pinpointed the break under the insulation without needing to strip wires. No more guessing or replacing parts blindly.Simple Setup:probe the wire, and the tone leads you straight to the issue. No training needed—plug and play.Worth Every Penny:Even if it only works once, it pays for itself in time saved. This tool turned a nightmare into a quick fix.Compact and Durable:The kit is lightweight, and the build feels solid. I tossed it in my toolbox with no issues.

Worth the money and the purchase especially long trailers.

It works good it is definitely easy to use, you really don’t even need that long of a cable for the little box as it just connected to a positive and a ground while the wand does the rest, I just wished instead of it beeping and the sound dying off as you loose connection it was the opposite so you don’t have to listen to the sound the entire length of the wire especially if you are working on a trailer to a tractor. It’s a pretty durable plastic as I have dropped already and it’s still together and working just after I found the break in the line I had to re-check it to make sure lol. The cable length I guess does work if you have wires to far from a ground. But it deff reads the voltage in the positive line you are running to see where the break is at.

Good bang for your buck!

As a master automotive technician with over 23 years of hands-on experience majority of my day to day involves in diagnostic work. I'm always on the lookout for tools that make the job more efficient and accurate. The V210 has quickly earned a spot among my daily go to diagnostic tools, especially when it comes to chasing down wiring issues like open or short circuits.Recently, I had a vehicle with an open fuse issue caused by an alternator wire that had broken at the connector and was shorting to ground. Using the V210, I was able to quickly pinpoint the issue without any guesswork. The process was smooth and painless, this tool made a potentially time consuming job quick and straightforward.What sets the V210 apart is its simplicity and effectiveness. It’s compact, easy to use, and extremely helpful for electrical diagnostics. If you do any kind of wiring or circuit work, this is one of those tools that will absolutely save you time and headaches.With all that being said, I do have two suggestions/recommendations that I hope the manufacturer considers in a future update:Continuity Testing with Audible Tone, Currently, the tool uses an LED indicator for continuity checks. Adding an audible tone would allow users to hear confirmation without needing to keep their eyes on the device, especially helpful in cramp areas like under dash or when working alone.Receiver LED Indicator: The receiver unit relies solely on an audible beep, which can be difficult to hear in a noisy shop environment. Adding an LED visual indicator would make the tool more accessible, especially for those who may be hard of hearing or working in loud areas.Overall the V210 is a highly capable and user-friendly tool that’s already proven its worth in my daily workflow. With a couple of small improvements, it could be nearly perfect. I highly recommend it to any tech who regularly works with vehicle electrical systems and it's very affordable!

Very useful tool for finding wiring problems in complicated modern cars.

Very useful tool for sorting out wiring problems in a complete engine wiring harness. One can follow the tone trough the wire to find a short or open circuit. A great tool when needed. It was a good price so wasn't sure how useful it would be. A little static but otherwise fine for a low price. Money is tight for me currently with serious disease so finding a useful tool that doesn't cost $1K is a blessing when dealing with complicated poorly labeled wiring.
