Product installation
The correct installation method can avoid measurement error. The inertial measurement unit
produces an absolutely smooth surface by grinding on the underside and measuring surface for
installation .The following points should be made when installing the sensor:
Finally,after the product is tightly attached,screws should be used to fix the IMU to ensure tight
fixation,smooth conduct and stable rotation.Measurement errors caused by acceleration and
vibration should be voided.Bear in mind that the screw only plays a fixed role and doe not have a
positioning function.The screw hole of the IMU is processed into an elliptical shape for easy
adjustment.
First of all, to ensure that the sensor mounting surface and the measured surface completely close,
the measured surface should be as horizontal as possible, so that we can reduce installation error.
Secondly,when the product is installed,the bottom surface of the IMU and the body should be
coincident,and it is gently pushed to make the measurement surface of the IMU coincide with that of
the machine body,so that both surfaces are tightly attached,and there is no angle in Fig.A and
Fig.C.The correct installation is shown in Fig.B and Fig.D.
