Review on Testo 0590 7601 Digital Multimeter by Wiktor Barczuk ᠌
It's not a good product, it's a pity that I spent money on it.
Previously, I already purchased from another supplier and used the device, there were no comments. The other day I bought the same one from MEGEON. To say dissatisfied is to say nothing. The device was purchased for professional use. Current measurement accuracy is disgusting! The error reaches 50%! I am enclosing a photo of checking the current measurement with a verified calibrator: when setting the current to 20 mA, the multimeter shows 13 mA!
- Build quality.
- Current measurement accuracy is extremely low and not suitable even for amateur use. When measuring a current of 10 mA, the error is about 50%! Perhaps I came across an uncalibrated device, I had already used such a device before, there were no comments.
