Page 5: Introduction
Introduction The WT901SDCL is a multi-sensor device detecting acceleration, angular velocity, angle as well as magnetic filed. The small outline makes it perfectly suitable for industrial retrofit applications such as condition monitoring and predictive maintenance. Configuring the device enables the customer to address a broad variety of use cases by interpreting the sensor data by smart algorithms. -

Page 35: Bandwidth
1. The higher rate of bandwidth setting will lead to the higher fluctuation in data waveform. Conversely, the lower rate of bandwidth, data will become more fluent. For example: Bandwidth as 20Hz, Output rate as 10Hz. The waveform is very steady. WT901SDCL | manual v0707 | http://wiki.wit-motion.com/english - 35 -... - Page 36 For example, if the bandwidth setting is 20Hz, retrieval rate as 100Hz, there will be 5 repeating data. If you prefer there is no repeating data, it is required to increase the bandwidth more than 100Hz. WT901SDCL | manual v0707 | http://wiki.wit-motion.com/english - 36 -...

Page 37: Restore Factory Setting
2.4.10 Restore Factory Setting Command method: Step 1: Connect the WT901SDCL module and the computer through the cable that comes with. Step 2: Click the Settings tab, and click to “Reset”. Step 3: After restoring the factory settings, you need to power on the module again. -
Page 38: 6-Axis/ 9-Axis Algorithm
9-axis algorithm: Z-axis angle is mainly calculated and analyzed based on the magnetic field. Z-axis angle will have few drift. The default algorithm of WT901SDCL is 9-axis. If there is magnetic field interference around installed environment, it is recommended to switch to 6-axis algorithm to detect the angle. -
