When looking at a used DRO, just the display with no scales attached, if it displays any digits other than 0's does that indicate there is something wrong?
 
It's impossible to say. My experience with the Acu-Rite readouts is that they'll display an error message if they were powered off then back on - this to keep you from thinking that they are really at the same 0,0 as before the power failure; I'd think that any other manufacturer would have a similar feature.
 
The ones we use on the mills at school, when you turn them on you have to hit "enter, clear" and then move the table a bit in the x and y axis before the dro starts working.
