About calibration
Calibration is performed for matching the F372A to a strain-gage sensor. The following two types
of calibration are available for the F372A.
● 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:
2.001mV/V (rated output) - 100.0kg (capacity)
● Actual load calibration
Apply an actual load to the strain-gage sensor and enter the actual load value by the keys for
calibration. Calibration is accurately performed with reductions in errors.
