Finn Junkermann –
I’ll start with the features. Instruction only on hieroglyphs, a device for the domestic market is possible. The charging socket is hidden under the case, in some working conditions this is a plus, for the house it is controversial. The voltage begins to show starting from 0.49 volts, although the instruction declares 0.6.
Of the minuses, the accuracy of the voltage measurement, volts up to 5 everything is in order, with an increase the error increases and is quite noticeable. Resistance and capacitance measures well. When you charge the screen, turn off the screen and sit on the idea of charging or not. Well, what for me covers all the disadvantages-a separate choice of ranges. You just want to turn on the call (it works instantly), you only want to measure the resistance, and you only want to check the diodes without a boring squeak. Thank you very much to the seller!
Bonnie Montes –
Checked, it works. Everything is great!
Nour Hartman –
It’s compact and great. The degree of perfection is high. thank you.
