I think my power supply just broke. I was working on a lab and the 5V supply suddenly dropped to 1V. I verified my meter is good. I tried to calibrate and when it prompts me to measure 1V I get .987V, then when it prompts me to measure 5V I only get 1V. It is the same for the negative supply. Is there any way to fix this or is the device broken? How would I go about getting a replacement?
