Zero Adjustment
To ensure accurate weighments, a zero adjustment must be done prior to first use. To perform a zero adjustment,
1. Ensure the scale is sitting on a level surface.
2. Check the eye loop area on the scale to ensure that the scale pointer is equally balanced in the eye loop.

3. Turn the zero adjusting screw until the scale pointer is in the center of the eye loop when set to zero.
4. The scale is now ready to weigh patients.
The patient should be completely seated in the chair, not leaning forward, and having feet firmly
positioned on the footrest assembly while being weighed.
