3.5 REPLACING THE FUNCTION LABEL
The Function Label may need to be replaced. (See Chapter 5 for parts information.) Use a broad
blade, such as a wide X-Acto
™ knife, to remove the label. Clean the glue residue from the Housing
surface. Then carefully place the new label where the old one was. (See Figure 3-5.)

3.6 DOWN-STOP ADJUSTMENT
The purpose of the down-stops is to protect the load cell from physical damage. The down-stops are
created by contacting bosses in the Base and adjustment screws or bosses in the Sub-Pan. The NV
models have 3 down-stops, left, right and center near the load cell attachment to the Sub-Pan. The
NVT models have 5 down-stops, left-front, left-rear, right-front, right-rear and center near the load
cell attachment to the Sub-Pan.
NV models with capacity greater than 2kg and NVT models with a capacity greater than 10kg do not
have adjustable down-stops. The down-stop bosses on the Sub-pan are designed to be at the
correct distance to protect these load cells. The smaller capacity load cells require the down-stop
clearance to be decreased for proper load cell protection. Adjustment screws are placed in the Sub-
pan down-stop bosses to reduce the clearance, see figure 3-6.
