Sensor Calibration

Sensor calibration ensures that pressure, position, temperature, and other feedback signals are accurate and reliable.

Calibration Preparation

Before calibration, confirm that the machine is in a safe state, the sensor wiring is correct, and the reference measuring instrument is available if required.

Position Sensor Calibration

Move the axis to the reference position, confirm the mechanical zero point, and then set the displayed position according to the calibration procedure. After calibration, run the full stroke slowly and check whether the displayed position changes smoothly.

Pressure Sensor Calibration

Release system pressure before setting the zero point. Then apply a known pressure and compare the displayed value with the reference gauge. If deviation exceeds the allowed range, adjust the calibration coefficient according to the system procedure.

Temperature Sensor Check

Compare each temperature-zone reading with a reference thermometer or known temperature condition. If the reading is abnormal, check the thermocouple type, wiring polarity, and temperature module configuration.

Notes

Calibration values directly affect machine control accuracy. Only authorized engineers should modify calibration parameters. Record the original value before adjustment.
