Abstract A in-situ calibration of CBT-type borehole-tiltmeter was designed for correctly understanding the drilling state.The remote calibration system takes RS-485 bus，as the basis and takes the stepper motor as the core.It is realized to calibrate remotely the sensors grid valued and linearity of the CBT-type borehole-tiltmeter.
