Note:
Junction box assembly 67171 has four (4) extended range, multi-turn potentiometers, one
for each load cell. If you have difficulty cornering the platform, turn all potentiometers to the
fully counter clockwise (CCW) position until a clicking is heard when turned. With the weight
on the lowest reading corner, turn the corresponding potentiometer clockwise (CW) to read
the same as the highest reading corner. Repeat this procedure for each corner until the
platform is properly calibrated.
Note:
As you move the weight(s) from corner to corner, do NOT zero the scale. Remember at this
time you are only adjusting the corners to be the same, not performing a correct calibration.
