Agilent E3634A output voltage after power off

[wictor]

Hi!

I have E3634A power supply and it's working fine during normal use. But when I power it off, output voltage starts rising and can easily go up to 10 volts(measured by DMM without load). This could potentially break some device if it is not disconnected. I guess this is not normal and I would like someone to test with similar unit, how it behaves.

Thanks,
