Operation
Zero Balance Adjustment
The scale should be checked periodically, particularly when moved, by following the instructions
below:
Note: A flat head screwdriver is required.
1. Ensure that the scale is located on hard, flat, and level surface. Step on and off scale
several times in order to align all internal parts.
2. Place both poise weights on the “0” value on both bars. The beam pointer should float
gently up and down, and not touch the top or bottom of the trig-loop.
3. If the beam pointer is not centered in the trig-loop opening, rotate balance ball screw to
correct the beam pointer.
