Note: 1, The update time is the time it takes for the sensor’s biaxial angle value to be updated once. Therefore, in the question and answer mode, the transmission of the next angle query command should be kept at least 40 ms apart from the end of the previous angle query command.

Installation Instructions
Improper installation can result in large angle measurement errors. Please pay attention to the following two points
when installing：
①: ‘Two sides’ means that the mounting surface of the sensor is completely close to the mounting surface of the object
to be measured (the mounting surface of the object to be measured should be as horizontal as possible), and no angle
can be generated (such as the angle a in the fifigure A). The correct installation method is shown in Figure B.
②: ‘Two lines’ means that the axis of the sensor is parallel to the axis of the surface to be measured, and the two axes
cannot be angled (such as the angle b in Figure C). The correct installation method is D.
