The two contacts do not work there is short!

Good quality and works well

Good product even if the accuracy is not its strong.

The installation is very simple and the operation is intuitive. Unfortunately, the check interface does not allow configurations related to the scale to be used, in fact the watmeter scale backdrop is preset to 20000W but if I have to check a reading of a few W is difficult to read. On the contrary, the measurement of the ammeter is in mA so I have to read 4 or 5 digits to understand the absorption (20000 W at 220V are about 90,909 A or 909ma).

Lastly, the fluctuation of the readings. At constant load the measurement is always fluctuating, probably due to the detection scale used.

For non-professional use it is certainly a valid product, I doubt that in professional fields it can be taken into consideration.

I really liked
