The calibrated uniform field is a 1.5m square vertical plane 0.8m above your ground plane and 3m from your antenna, usually the tip (the size of the vertical plane and the antenna distance can be smaller but that's not the issue here). The EUT is placed so that the panel you are testing is illuminated by the vertical field ie the part of the EUT nearest to the antenna should always be 3m away. I know this sounds rude and I don't mean it to be but if you weren't sure that the uniform field was a vertical plane, how did you calibrate it?
