The Corner menu item is for balancing the load cell outputs using weights placed over
each corner of the scale. See Corner Balancing on page 32.
The Section menu item is for balancing the load cell outputs using weights placed
between load cells or sections of the scale. See Section Weight Adjustment on page
32.
The Swap menu item is for replacing a bad load cell with a good one and still be
assured the accuracy remains high. See Sensor Swap Procedure on page 33.
Corner Balancing
Highlight Corner and press Enter. Follow all the on-screen prompts to complete the
cornering process. When completed you will be asked if you want to perform a Ghost
calibration. Answer accordingly and follow the instructions. Ghost calibration is not
legal for trade.
When finished, follow the Zero and Span procedures in your indicator’s service manual
to finish the calibration.
Section Weight Adjustment
For optimum section calibration, enter the Weigh Bar nominal span Factors and cell
capacities in ZTools before performing Section weight adjustments. If no span values
are available for the sensor, you MUST enter 1 for a value. Leaving it at 0 disables
section weight adjustment.
As long as you use the same weight the system will adjust the sections correctly.
Remember, a minimum of 10% scale capacity is recommended.
As long as you use the same weight over each sensor, the system will corner
