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.
