3-1. Calibration
"Calibration" means matching the F701+ with load cells. There are two types of calibration procedure,
"actual load calibration" and "equivalent calibration".
<Actual load calibration> ..... Calibration by applying actual weight or pressure to the sensor
<Equivalent calibration> ...... Calibration by directly inputting electrical signals equivalent to
the electrical signal changes pr
oduced when actual weight or
pressure is applied to the sensor.
3-2. Load cell junction
Multiple load cells can be connected to the F701+ by using junction boxes or terminal blocks.
■Single load cell
■Three load cells
