Figure 3-21: Calibration Values Screen, Zero in Focus

• Shift Values—Used for POWERCELL and PDX scales only. The following

screen shows values used to adjust gain for each load cell in a multiple load

cell system. The values compensate for difference in response between cells.

The load cell numbers represent the node cell addresses. Where more than 12

load cells are present this screen displays a scroll box to reveal further rows.

The diagnostic purpose of the Load Cell Output and Shift Values screens is to

permit a technician to confirm valid calibration values were obtained when the

calibration routine (Setup > Scale > Scale

> Calibration) was carried out.

Figure 3-22: Scale Shift Values Screen

• Diagnose Cell—Used for POWERCELL scales only (but not POWERCELL PDX).

The purpose of the Diagnose Cell screens is to allow the technician to verify a

load cell’s node address and raw counts. If the cell that is being diagnosed

has a known address, select that address from the Load Cell Address selection

box. If the cell address is unknown, then select Connected Cell. If the cell is

faulty or it has an invalid address, the terminal will fail to communicate with

the cell. If the cell responds correctly, the node address and the cell counts will

be displayed on the screen (Figure 3-23).
