  The force value and deformation can be automatically calibrated.After our debugging is completed,if the user feels that the displayed value is inaccurate or the measurement and control parameters have been changed,they only need to click the automatic calibration button,and the system parameters will return to the state they were in during debugging.
  (8)The zeroing of the system adopts digital design
  With just a mouse operation,two acquisition channels can be zeroed.The system generally only needs to be zeroed once,and under normal use,the system will automatically return to the true zero point.
