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.
