Fairbanks Aegis Heavy Capacity PLF-6200-HQ Series - Manual (Page 7)

C. Place a concentrated weight (25% of platform capacity) on corner 1, then move to
corner 2, corner 3, and corner 4, noting the displayed reading on each corner.
D. If corners require adjustment:
1) Place the concentrated weight on the corner displaying the lowest weight
and use the appropriate potentiometer to change the displayed weight to
read the same as the highest reading by turning the potentiometer CW.
Repeat while rechecking all corners until there is no error. Perform a Zero
reference check with an unloaded platform and repeat the corner test to
ensure all readings are the same before proceeding

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