HAMA B7047770 an Product of 6-2017,  Even so this received too many bad reviews from the Greek market because it was stop working in about few months to a year of time.


One friend of my, he gave me as gift one of those also dead.   :)

Internally and under the large Blue capacitor there is an SMD resistor (surface mount resistor), which the factory made the mistake to add one half  from the required wattage.
The smaller in watt resistor this is suffering from high heat and eventually it become open circuit.

Unfortunately the vast majority of consumers can not benefit from this repair tip, but possibly some will do.  ;)

Enjoy the pictures and the hidden truth.   

Product notes
I got surprised by discovering that HAMA 047770 this has digits refresh rate of one times per second.
When no name similar meters are very slow and update the digits every six seconds.
The specific HAMA this is a little high at volt meter about six volts higher at 230 volts range.
Either way the WATT calculation and the AC current measurement this is correct.
