OpenScope MZ Channel 1 power supply stays on and will not adjust


Recommended Posts

Hello Everyone,

I have an OpenScope MZ and the channel 1 power supply stays on and will not adjust from the value in the picture. I have re-flashed the firmware. Calibration attempts have all failed, I suspect that this is because the Voltage is too high to be adjusted. Does anyone know a fix for this? 

Thanks in advance,

To add more background to this. I work for University of Cincinnati. My department purchased 100 of these devices to facilitate teaching electronics lab online. This is the first semester they are in use. We have had no problems so far. This past week the students used the dual power supply for the first time this past week and now I have two units out of about 88 that have this same problem. The second unit is stuck at around 1 Volt. I have searched the forms and reviewed the content that Digilent has made available.
