I’ve run into a bug, where the DSO Nano displays (part of) the correct signal, but at an inflated voltage on the display (and with the “V avg” measure).
[]Test signal on 1V/div is 2.0v avg and displays correctly. Test signal on 2V/div is off the screen and 25.92V avg displayed. ???
[]Measuring my signal generator’s 5.1V output shows 81v avg.
Measuring small signals at 1V/div is correct.
when you change to 2V/div , do you change the triggering level to the correct place ,too.
May be you can save the picture of the screen with the Dat2Bmp Tool and post it here , and we can get more detailed about your problem and give some suggestion or processing.
can you test the 0.2V and 0.5V /DIV and the 5V 10V /DIV ~ the former is right and the the latter is incorrect, that may be something wrong in the channel of the X6 - -|||
