weight from a load cell.
Rotating a POT counterclockwise will decrease the
added weight from a load cell.
Adjusting a POT will affect the other two POT
readings.
The goal is to have all three corners display the same
value.
6. Place the 25 lb weight on each corner of the
CubiScan 125. Figure 18 shows which CubiScan 125
corner (where the load cells are located) corresponds
with each POT.
7. Choose the two corners that are the closest to 25 lb.
These will be your first and second corners. Move the
weight back and forth between them. Adjust the
appropriate POT until the displayed weight values
for both corners are the same (this does not
necessarily need to be 25 lb).
8. Move the weight to the third corner. Move the weight
back and forth between corners one and three.
Adjust the POTs until the same weight value is
displayed for all three of your corners.
9. When all three corners read approximately the same
weight, the load cells are balanced.
10. Replace the load cell summing box lid and secure it
using the screws from step 5.
11. When everything has been replaced and the load
cells have been balanced, you need to recalibrate the
scale. For instructions on calibrating the scale, see
“Scale Calibration” on page 14.
