Weight Calibration - RSscan footscan User Manual

6.1 Weight Calibration

The values of the footscan device are proportionate to the pressure on each sensor,
up to a factor. This weight calibration factor is identical for all sensors but might vary in
time due to wear. Footscan 9 relies on an up-to-date value of the weight calibration
factor to guarantee accurate measurements. Weight calibration recomputes the
calibration factor for each device.
Weight calibration uses a measurement of a subject with known weight. Based on such
measurement with known characteristics footscan 9 is able to determine the weight
calibration factor accurately.
rs scan recommends performing weight calibrations regularly. Set the desired time
interval between calibrations in the Settings dialog (Section 6.4).

The weight calibration needs to recognize at least one foot to succeed. The
accuracy of the weight calibration increases with the number of recognized
feet. Generally 6-8 feet suffice to obtain a reliable calibration factor.
rs scan recommends to send the footscan system to rs scan yearly for
replacement of the Pressure Sensitive Layer (PSL) and calibration. Contact
