Topdiag P200 Power Circuit Probe Kit - Test Light Automotive Circuit Tester Circuit Breaker Finder Tool, Relay Tester Multimeter, Oscilloscope, Fuel Injector Tester - 9~30V

En mi criterio está muy buena la herramienta y se ajusta a la description del fabricante

It was just to large and wasn’t very practicable for me, me ordered thier original one that I bought earlier this year

As someone who hates to take a vehicle to a repair shop and hates a large repair bill even more, this is a great tool to have. I own multiple German and Italian cars that have questionable electronics and plenty of Grimlins that need to be found.Topdiag put together a unit that will make life easier. The manual walks you through the basic operations and helps you learn the functions that you may be weak in. All the extra items and storage case complete the package. It's a really good value on a quality product.

The circuit probe tester by Topdiag is made in PRC (china). The P200 does a lot of different tests that the description mentions. The handle has only a few buttons, so there is some menu hunting when you change test type. I would prefer more adjustments and options on the oscilloscope, but if your checking a CANbus TTL signal, it works fine. It's bigger than a power probe, so getting this into tight places was not ideal for me. The power cord was plenty long for my purposes. I did appreciate the various end tips for the tester for use out of the box. This is a better tester when you find it for around $100.4 stars

The media could not be loaded.  I love all of the capability packed into this circuit tester, especially that it includes a one channel oscilloscope function.I most frequently use circuit testers like this for fuse testing (see brief video)... in that respect I do prefer my classic Power Probe 3 because it has a different tone for positive and ground while this tool only returns a tone on positive voltage readings.The product description of this product heavily features the 0-5v power supply feature which may make you think it won't provide power beyond 5 volts but it will supply battery voltage with the component activation mode. Note though that the circuit breaker in this probe will only allow a maximum of 18 amps to be provided to a component (see screen shot with circuit breaker dialed to the max).I hate the hard plastic cases supplied with so many tools and definitely prefer the type of case included with this tool. Build quality of the tool and the accessories looks good. The red extension cable should remove any concerns about tool bulk preventing probe tip access in tight places.Very happy with the many capabilities of this tool especially at the price. I'll still reach for my Power Probe 3 for fuse testing but I'll be using this for more advanced circuit testing needs and especially look forward to my next relay testing and oscilloscope testing cases.

The media could not be loaded.  I'm very pleased with how well the circuit tester works. It is extremely well-made and great quality. It is made from a harder style ABS plastic. The buttons on it are rubber coated and feel very nice when you actuate them. You can definitely tell this is a quality product. It is very easy to use and the instruction manual is extremely easy to follow. The screen is a good size and illuminates very brightly. It is very easy to read and toggle between the different modes in settings. I don't know much about troubleshooting electrical equipment, but this machine makes it easy and it's very easy to use for a newbie like me. It is basically self-explanatory. If you have a lot of experience than I can only imagine how well this piece of test equipment will work for you and make your job so easy. There are multi functions that you can use this machine for as it tests relays, fuel injectors, etc... There's also a smart function which will figure out voltage and Ohms. This device has a fuse at the ground so it is protected in case you accidentally touch a hot wire so you will not burn this thing out or hurt yourself. Overall, I'm very happy with this piece of test equipment. It's great quality and good value for the money. I recommend it.

This rugged probe, gives you all the functionality of a multi meter, relay tester, and oscilloscope. Test bulbs, fuel injectors and all thing circuit related with this tool. You can also check for bad grounds, upgrade via USB cable, and comes with a nice case. Covers 9v-30v systems. 20ft of cable slack with alligator clips. Firmware is upgradeable with pc. Color LCD is easy to read. All in one tool for all your low voltage needs.

I don't think I'd trust the oscilloscope function for critical diags, but everything else works fine. This tool is super helpful for testing all kinds of electrical issues. Definitely worth having as an option.
