4. CALIBRATION METHOD
4-1. What is Calibration?
Calibration is performed for matching the F130 to a strain gauge type sensor.
That is, F130 must be properly adjusted to indicate 10.00kN when an actual load of 10kN is placed
on the strain gauge type sensor.
4-1-1. About Calibration Methods
There are two methods of Span calibration: Actual load calibration and Equivalent input
calibration.
Actual load calibration
By this method, calibration value is registered by the value of the actual load applied to the strain
gauge type sensor.
Error-less accurate calibration can be performed.
Equivalent input calibration
By this method, calibration value is registered from the rated output value (mV/V) and rated capacity
value of the strain gauge type sensor. This calibration method using no load can simplify work.

A data sheet is attached to a strain gauge type sensor at the time of purchase.
For Equivalent input calibration, the "rated capacity value" and "rated output value"
described on the data sheet are set to the F130: therefore, it should be carefully
stored after calibration.
