How accurate is the scale on VersaCare® Bed?
 

The scale system for the VersaCare Bed has an accuracy of 1% and an operating range of 0 lb to 500 lb (0 kg to 227 kg). The scale display and controls are located on the flip-up control pod on the head-end siderails. 

The scale is very sensitive. The weight reading will be most accurate if the bed is not touching anything. This includes the headwall, lines such as pendant controls, ventilators, or drainage bags. Anything that affects the weight on the bed even slightly will cause an incorrect weight to appear on the display.
