2. NV models and the NVL20000 model require a load cell spacer to be positioned between the
load cell and the Base. Position the load cell back into the lower housing. NVL and NVT models,
place a lock washer then a flat washer on the load cell screws (NV models do not use the
washers.). Turn the scale over to install the (2) load cell screws. Loosely tighten the screws so that
the load cell can be aligned in the housing. While holding the load cell, fully tighten the screws. The
screws should be tight enough so that the load cell does not move when pushed from the side.
Verify that the load cell is centrally located between the ribs.
3. Turn the scale over onto its feet. Position the PCB on to its locating pins. Coil the excess load
cell cable in front of the load cell.
4. Slide the AC jack into its position in the lower housing. Route the AC adapter cable as shown in
Figure 3-4.
