EXAMPLE: OB30L-F3 System
Balancing Weights:
English = 5000 lb. Metric = 2000 KG
Graduations: English = 5 lb. Metric = 2 KG

From the above results, it can be seen that cells 1 and 3 must be adjusted down
to read 4990 lbs. (1996 kg in the metric example). First, the trimmer for cell 1
is turned clockwise to bring the reading down (step 6(c)).

Next, the trimmer for cell 3 is turned clockwise to bring its reading down.
Because this cell is being adjusted by three graduations, the procedure in 6(d)
should be followed, adjust cell 3 down to 4985 lbs. (1994 kg in the metric
example) and check for a zero shift.

The unloaded reading is found to be –5 lb (-2 kg), indicating a zero shift. The
scale must therefore be re-zeroed, and cell 3 checked again.
