MODEL D500M PORTABLE BEAM SCALE ASSEMBLY MANUAL AND OPERATING INSTRUCTIONS
IV. SHIFT (as needed)
A. TEST
Place a half capacity test load in the center of each quarter of the platform, or use a quarter capacity test load over each
load pivot successively.
If a correction is not needed, proceed to the operating instructions. In a mechanical base, shift refers to the pivot distances
of the levers. If, on a lever, the distances are equal, then a lever is said to have no shift error. Also, two levers which have
the same ratio will have no shift error.
B. ADJUST
The lever illustration of the D500M designates the pivots as follows:
F - Fulcrum Pivot
L - Load Pivot
P - Power Pivot
C - Center Connection
