Hi community,
thanks for your replys!
@Rejected666: I'm very sorry, I made a mistake in writing. At the top of the adapter is written
"12V (then the DC-sign (line at the top;three dotted points at the bottom)) / 500mA 6VA". So I think the output is DC, right?
@James C4S: I also made the same mistake above: I confound the AC sign with the DC sign. At the voltmeter I have chosen DC. I also instslled a led with a resistor and the result was nearly the same yesterday.
Very very very strange: Today I made the same measurement. When I chose the scale 200V at DC (!), the display shows 283! And there is NO dot anywhere in the display. It's really distressing for me to say this strange things. I think I must go to an electronic system shop to ask about this strange thing. I'm really confused! But thanks a lot for your answers!!!
Kindly regards,
Andy
