Incorrect measurement for every voltage

[Andrea Castellaneta]

Hello,

I am writing as Omnigrasp, a spin-off company originating from over 7 years of research in soft robotics laboratories at EPFL in Switzerland and Politecnico di Bari in Italy. Our work mainly focuses on electroadhesive grippers, which work with high voltages. We have been using the Digilent Analog Discovery 3 oscilloscope for a little less than a year and rely heavily on it for sensing, while ensuring careful protection (measured voltages always below 10 V).

Recently, we encountered an issue: the oscilloscope displayed a constant value of 29.611 V during every measurement. It is important to mention that an electric arc occurred in our circuit the day before, although it did not directly impact the oscilloscope. Nonetheless, we are concerned that this event might have caused damage to the device.

For your reference, we have attached the serial number of the oscilloscope and a screenshot of what appears on the display.

Could you please provide guidance or support on how to address this issue? We are willing to answer any questions that may arise and if we fall within the warranty return policy, we are open to shipping ours back and waiting for a new device. We appreciate your assistance and look forward to your response.
