4-1 General
There are three ways to calibrate zero and span.
Digital span calibration Calibrates with load cell output voltage.
Actual load calibration Calibrates with weights.
Gravity compensation Sets the know acceleration rate (“g”) for your location
4-2 Digital Span Calibration
This is calibration using the load cell output voltage (mV/V) instead of weights. Function CAL-19 and
CAL-20 configures the calibration function. See {Appendix C: FUNCTION LIST: CALF—Calibration
Functions}.
1. Enter the zero voltage.
Enter the load cell output voltage at the zero point with numerical keys.
2. Enter the span voltage.
Enter the difference of the load cell output voltage between at the capacity and at the zero point.
3. Relate the span voltage with weight.
Relate the span voltage with displaying weight.
4-3 Actual load Calibration
Before actual load calibration
AD-4403-FP ST Series
Weighing unit (CAL-01), decimal point position
(CAL-02), and, capacity (CAL-03) should be set in
prior to calibration. See {Appendix C: Function
List}
•
Perform “Gravity compensation” before the
actual load calibration. ( “g” must be set with or
without the actual load calibration.
•
The scale has been calibrated at factory before
shipment. However it must be re-calibrated at
your location due to a change in gravity
acceleration.
•
Turn the adjustable leveling feet until the level
spirit shows that the platform is level before the
actual load calibration.
•
Connect the load cell cables before turning the power on. Calibration may not be done properly if
connected after the power is turned on.
•
Set the calibration disable switch (inside the case) to the ON position to perform calibration.
•
In order to avoid influence by temperature drift, carry out this calibration 10 minutes or more after
turning on the power.
