So I got a new power supply a couple months ago and I am getting a reading of 25 volts DC on my multimeter when I touch the black probe to ground terminal on the power supply and the red probe to the front bnc connector on scope. I get 25 volts DC on scope, frequency counter and cover screw on Wall outlet. I had a professional electrician check out all my wall sockets and he said everything was good. At first I thought my scope had a hot chassis but I got another scope and a frequency counter and all say 25 volts on chassis. What do you think???
Are you reading the correct scale on the multimeter?
