  • Page 36: Calibration Procedure

    CALIBRATION PROCEDURE 4-1. How to calibration "Calibration" refers to an operation whereby matching between the F350 and a strain gauge sensor is obtained. The F350 uses the two calibration methods as described below. ■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.

Ch1 Ch 2 Press five times.
  • Page 39 The maximum excitation voltage value of the strain gauge sensor connected to the F350 should always be larger than the set bridge voltage. If the excitation voltage of the F350 is larger than the maximum excitation voltage value of the strain gauge sensor, the strain gauge sensor may heat or break.
  • Page 40 4　CALIBRATION PROCEDURE ⑤Zero calibration Register the zero point with the sensor unloaded. Also, if there is any initial load, such as a jig, for measurements, the zero point can be registered with the initial load applied, but the signal input range needs to be considered as the initial load is subtracted from it.
  • Page 41 4　CALIBRATION PROCEDURE ⑥a.Equivalent input calibration See the test report of the sensor, and register the rated output value and the value you want to display at that time (rated capacity value). Input the rated output value and display value (rated capacity value) successively. Equivalent input calibration is not executed by simply inputting the rated output value.

    A D/A converter is provided for obtaining analog output synchronized with the indicated value of the F350.The analog output ranges are -10 - +10V output and 4 - 20mA constant-current output. By using the D/A zero setting and D/A full scale setting functions, analog output can be obtained between zero (0V, 4mA) and full scale (10V, 20mA) with respect to the predetermined digital value.
