4. CALIBRATION
Calibration is performed for matching the F370 to a strain-gage sensor. The following
two types of calibration are available for the F370.
◇ 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)
as indicated for a load.

Strain gauge sensor
A data sheet is attached to a strain-gage sensor 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 F370.
