I have come accross a dual bench power supply that has both -ve oupts terminalls connected to Earth(the case) through a 6.8M ohm resistor.
I have always assumed that electronic bench power supplies had floating outputs.
This is the first time I have come accross this on a PSU. I noticed because it was affecting my measurments with a scope.
Is there any reason to connect the -ve output to earth and is it common?
Thanks,
