Faulty DSO112A?
Posted: Sun Feb 03, 2019 8:50 am
I have a brand new DSO112A which only shows maximum DC voltage (straight line) no matter whether the input is connected to signal or not. I have measured the wires, checked the connectors as well as all the soldering. Otherwise the s/w seems to be working fine ie. display and menus work ok. If I switch the measurement display on, it shows max voltage and frequency 0 Hz in spite of legal input from signal generator or not.
I have a good knowledge of electronics so I could fix the equipment if there is a schematic and pcb layout available. Or is there any known issues I should check first?
