Load Cell Zero and Full Weight Calibration
The WSB has a set of load cells for weighing the weigh bin. The load cells must be calibrated periodically with zero
and full weight calibrations for proper operation and accurate weight reporting. The zero calibration routine should be
performed routinely to tare the load cells back to zero or near zero when necessary. The Full weight calibration should
be performed periodically to set the calibration slope. Full Weight Recalibration of the load cells is recommended
every 6 months especially if totals are collected from the blender. The following instructions outline how to calibration
the weigh bin load cells, identified as the load cell assembly that weighs the removable weigh bin.
Before performing a Zero Weight Calibration or a Zero/Full Weight Calibration, verify the following:
If you are calibrating a WSD, *47 must first be disabled to perform a calibration.
After the calibration is complete, *47 can be re-enabled.
BE SURE
the weigh bin is EMPTY.
BE SURE
the load cell cable is plugged into the side of the controller.
BE SURE
the weigh bin is resting on the load cells freely and does not make contact with anything around it.
BE SURE
the air line to the weigh bin
’s dump valve is connected as it would be during normal operation.
BE SURE
The load cells and bin are not jammed in any way. To test for this, see that a light touch on the bin
causes the display to change. When the pressure is removed the display must return to exactly
where it was, plus or minus 1 gram. If this does not happen, bin is not entirely free to move. Check
EVERYTHING around the bin.
