Hello everyone, it's a relief to find such a generous group that shares their experiences and solutions. Unfortunately, for now, I'm on the side of those in need:
Yesterday I received my DSO2D10, and it had a problem from the very first moment. I've read all the threads and I suspect I'm going to have to request a replacement.
As soon as I turned on the oscilloscope straight out of the box, it showed a waveform of approximately 0.5V and 1.5KHz. I've attached the image at 500mV/div; the values are always in that range, although they vary. If I change the scale to 200mV/div, the waveform disappears, and I only find noise at 10mV/div.
By cooling it with air, I've been able to get it to start up properly, but after a minute it's malfunctioning again, and I have to leave it off for a while to restart it. If I don't, it turns on with the fault.
Software 1.0.3.0.0(230327.00)
Hardware 003.002.001.000.000.000.000.001
Firmware 3202
I shouldn't perform any updates before contacting my supplier to avoid jeopardizing any possibility of a replacement.
I haven't seen such a serious problem anywhere on the forum. Do you think it can be fixed without needing a screwdriver?
