3.0 Adjustments and Calibration The following sections describe adjustments that need to be made to the Summit SB-1000 Bariatric Wheelchair Scale. 3.1 Mechanical Adjustments To accommodate minor floor unevenness, the scale feet can be used to adjust scale height up or down a fraction of an inch. Adjust the feet by hand (lift the scale corner slightly with a pry bar) until all feet are contacting the floor equally.
With all potentiometers at full signal, place the test weight over one corner and record the indicated weight. Repeat the process for each of the other three corners. The load cell with the lowest corner reading is used as a reference point and will not be trimmed. Next, place the test weight over one of the other three corners and use that cell’s potentiometer to adjust the cell output down to the reference cell output. Repeat this procedure with the other two high corners.
