Re: Tek 475 no traces on screen

Put a DC blocking cap in series with your meter and put the meter on
an AC range to measure the ripple. It should be in the mv range.

Not that I have noticed. I measured the voltages with a DMM. I have the following stabilized voltages: +50.1 +15.1 -7.8 -14.8 +111 . I expected to get at least a line somewhere on the screen, but nothing. Again, I do not have an aditional oscilloscope to measure the actual ripple, I only have a DMM.

Is there any AC ripple on the other supplies?
