4. CALIBRATION
Calibration is performed for matching the F600AT to a loadcell. The following two types of calibration
are available for the F600AT.
◇
Actual load calibration
Apply an actual load to the loadcell and enter the actual load value by the keys for calibration.
Calibration is accurately performed with reductions in errors.

◇
Equivalent input calibration
Calibration is performed without an actual load by entering the rated output value (mV/V) and the
capacity (to be indicated) of the strain-gage sensor by the keys. Calibration is easily performed when
no actual load is available.
For example, the gain is automatically determined by entering:
as indicated for a load.
Loadcell
A data sheet is attached to a loadcell at the time of purchase.
The data sheet provides data including:
Capacity
Rated Output
non-linearity, hysteresis,input resistance,output resistance and zero balance.
Enter the capacity and the rated output value required for equivalent input
calibration into the F600AT.
