BWK217S Modbus Single Axis Inclinometer Installation The correct installation method can avoid measurement errors. When installing the sensor, please do the following: First of all, make sure that the sensor mounting surface is completely close to the measured surface, and the measured surface should be as level as possible. There should be no included angles as shown in Figure A and Figure C. The correct installation method is shown in Figure B and Figure D. Secondly, the bottom line of the sensor and the axis of the measured object cannot have an angle as shown in Figure E, and the bottom line...
