BW-AS400High sensitive low zero drift 3-Axis accelerometer
The correct installation method can avoid measurement errors. The following points should be
taken when installing the sensor:
First of all, to ensure that the mounting surface of the sensor is completely close to the surface to
be measured, the surface to be measured should be as horizontal as possible, and the angle shown in
Fig.A and Fig.C cannot be generated. The correct installation method is shown in Fig.B and Fig.D.

Secondly, the bottom edge of the sensor and the axis of the object to be measured cannot be
generated at an angle as shown in Figure E. The bottom edge of the sensor should be kept parallel or
orthogonal to the axis of rotation of the object to be measured. This product can be installed
horizontally or vertically (vertical installation requires customization), and the correct installation
method is shown in Fig.F.

Finally, the mounting surface of the sensor and the surface to be measured must be fixed, flat, and stable.
The actual installation direction is subject to actual conditions.

Connect the serial port hardware of the accelerometer correctly and connect the power supply.
Select the computer serial port and baud rate and click to connect to the serial port.
Click Start and the current data will be displayed on the screen.
You can download the serial debugging assistant directly in the official website (Technical
Service->Download Area), or you can use the more convenient and intuitive PC software. The BW-
AS400-1 serial port debugging software can connect the acceleration sensor to the computer for
data display. The software debugging interface is shown in the figure below, and other parameters
can be modified and set.
