When powered up both displays show the users last settings but do not

Ah, sorry.

After a few seconds they display the supplied values.

Ok.

and then revert to the

Which in case of the voltage and assuming it's not already current
limiting will be the same as the initial value and the current will be
the actually current being drawn (not the limit)? But the point was it

This is correct it will be the last user set values.

Ok good.

I do not know how long it retains these values as I have never left it
powered off more than few days.

I guess if they were held in some sort of NV RAM it could be
indefinitely. ;-)

Hope this has been of help.

Yeah, I think so John, thanks. ;-)
