One or two technicians previously weighed on a set of accurate scales makes an easy to move and portable test weight for larger scales.
Weight yourself or even two people on a known set of scales then walk around the hospital, but not too fast so you sweat and do not eat, drink or go to the toilet. Then double check your weight on your return to the workshop.
Two large or three small people wil do for bariatric beds scales.
