setting/verifying the Span Weight value executing this command will run the Hard Calibration process using
the Cal Tolerance, Span Weight, and Sensitivity parameter settings.
Span Weight Parameter
The Span Weight value is the weight of the object that is being placed on the scale to set the “High” calibration point with
respect to the “Low” calibration point set using the Cal Lo Weight parameter.
Span Weight is typically 80-100% of the expected maximum product loading on the load cells.
Hard Cal Process
Hard Calibration requires a zero point and the physical placement of test weights on the scale.
Set the zero point (Ref Weight) equal to the initial “live load” weight present on the scale. If the scale is
empty, the Ref Weight value should be 0.00. If any product weight is on the scale when setting this value, the
Ref Weight must be equal to the amount of load on the scale.
Navigate to the Hard Cal menus in the Webbrower or in the front panel display
1) Wait 12 seconds or more for the scale to stabilize. Turn off as much vibration and production
equipment as possible to achieve the best calibration.
2) Enter a value for Ref Weight or leave 0.00 if the scale is empty.
3) Press or click Do Cal Lo button to do the hard Cal Zero operation.
4) A “Cal Completed OK” message appears briefly if the first step of the calibration process was
successful. An Error number appears if the calibration was not successful. See the Error list in
the troubleshooting chapter for help in correcting the error.
5) Place certified test weights on the scale.
6) Enter a Span Weight value equal to the test weights placed on the scale.
7) Press or click the Do Cal Hi button. A “Cal Completed OK” message appears briefly if the calibration was
successful. An Error message appears if the calibration was not successful. See the error list in the
Troubleshooting chapter, for help in correcting errors.
8) The scale is now calibrated
