length checkout trouble

We do a length check out every morning. It's always within the allowable
0.059mm. Today we can't get the range or standard deviation under around0.200mm. We had the same trouble a couple months ago and had the ROMER repaired. For the last two weeks the length checkout was fine, but today bad numbers. We've cleaned everthing - magnets, table top, length bar, etc.
We've also reloaded the arm specs.
Does anyone have any ideas what might be going on?
Thanks...

Did you do a probe calibration? You didn't mention it in your post if you did.

If you did a probe calibration and it still gave you bad numbers on a length check, then it sounds like somebody may have accidently let the arm fall or bumped something too hard and your encoders need an adjustment. Romer Tech Support, as newguy stated, is the way to go then.
