Page 21: Digital Calibration (Calibration By Sensor Output Value)
8-3. Digital calibration (Calibration by sensor output value) At the time of purchasing sensor, the rated capacity (R.C) and rated output (R.O) declared on the calibration sheet can be used for the calibration for easier calibration. Measuring Mode key is being While pressed, press key. - Page 22 8-4. Actual load calibration (실부하 교정) If the actual load (load, displacement, pressure) is applied to the sensor and there is a difference between the value displayed in the indicator and the actual load value, the display value of the indicator can be changed to the actual load value. Up to 8 points can be stored. As the calibration interval is differentiated, the linearity of the sensor can be increased.
