I have an E3632A Power Supply that has recently stop working. I am not able to adjust voltage or current using the thumbwheel, but the thumbwheel adjustment will work in the display limit mode. When the output is set to on, the 'Unreg' annunciator automatically comes on. Voltage always measures -0.523V with a DVM. I am able to communicate with the supply using IntuiLink. I am able to adjust voltage and current values using IntuiLink but the output always measures -0.523V despite what the supply is set to. The display will show the correct value set by IntuiLink, but the output always measures -0.524 using an DVM.
Any recommendations on how to correct this would be appreciated. Thanks in advance.
