Faulty and Unreliable Voltmeter Scanner!

Using this product, our team found that it was incredibly difficult to use due to its complicated functions and lack of clear instructions. Not to mention, the readings that it provided us with were constantly inaccurate and inconsistent. The only positive aspect of this product is that it is lightweight and portable. However, this does not make up for its many downfalls. As a loyal customer of Tools and Home Improvement, I was extremely disappointed with this purchase and would not recommend…

Pros
  • Accurately measures frequency and voltage levels in real-time
Cons
  • Difficult to interpret readings without prior knowledge of transistor technology

Pretty accurate for its price

This gadget is amazing value for money. It is easy to use and calibrate. It correctly identifies the most common components. It's relatively accurate: I've tested it successfully with known capacitor and resistor values. I trust the values it returns. I have made it a habit to test each component before soldering it to the board. The only problem I have is that the battery drains very quickly. Now I connect it to an old DC power supply.

Pros
  • LCR meter
Cons
  • I don't remember but there was something

Chip pin broken during transportation

Once used, this can be a great electronic tool. I contacted the seller about a broken pin 28 of the chip and they promised me a replacement but it hasn't arrived yet. The reason I think the component is damaged is because not much attention has been paid to packaging and protecting the components for shipping. Also connecting a 28 pin chip to the included header would have helped, or a gasket. I think I should ask the seller for updates. I'll upgrade to five stars if it works, shame about the…

Pros
  • Industry and Science
Cons
  • Operating speed
