5-1. What is Calibration?

Operation of matching the F395 and sensor is called "Calibration".
For the F395, there are two methods of calibration as follows:
Equivalent input calibration
By this method, calibration is performed by simply inputting the rated output value (mV/
V, V, mA) of the sensor and the indicated value by keypad without using an Actual Load.
Calibration can easily be performed even if an actual load is not prepared.
Actual load calibration
By this method, calibration is performed by giving an actual load (displacement) to the
sensor and inputting the actual load (displacement) by keypad. Accurate calibration with
few errors can be performed.

5-2. CH1 Input Calibration and CH2 Input Calibration

Perform calibration with respect to each of analog input CH1 and CH2. CH2 may be set
for measuring the X-axis (displacement input). (The axis in current use is displayed in
the Axis setting under CH2 Input Calibration.)
