High Precision Dual-Axis Digital Output Inclinometer Installation direction The correct installation method can avoid measurement error. The following points should be made when installing the sensor: 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, can not have the angle shown in Figure A and Figure C, the correct installation is shown in Figure B and Figure D. B uneven surface generates the angle D uneven surface generates the angle Secondly, the bottom cable of the sensor and the axis...
