Page 5: Introduction
A sensor measures 3-axis angle, angular velocity, acceleration. Its strength lies in the algorithm which can calculate three-axis angle accurately. BWT61 is an CE standard accelerometer. It is employed where the highest measurement accuracy is required. BWT61 offers several advantages over competing sensor: •... -

Page 15: Calibration
Calibration Preparation: Make sure the sensor is “Online”. Calibration on PC software： It is required to calibrate for the first time usage. BWT61 | manual v0707 | http://wiki.wit-motion.com/english - 15 -... -
Page 16: Accelerometer Calibration
0, 0,1, the X and Y axis Angle is around 0 °. After calibration, the x-y axis Angle is accurate. Note: when putting the module horizontal, there is one G of gravitational acceleration on the Z-axis. BWT61 | manual v0707 | http://wiki.wit-motion.com/english - 16 -... -
Page 17: Reset Z-Axis Angle
Calibration methods as follow: firstly keep the module static, click the “Config” open the configuration bar and then click “Reset Z-axis Angle” option, you will see the the angle of the Z axis backs to 0 degree in the module data bar.

Step 1: Rotate the module 90 degrees around the X-axis Step 2: Place the sensor 90 degrees vertically Step 3: Click “Vertical” as install directions on “Config” menu BWT61 | manual v0707 | http://wiki.wit-motion.com/english - 23 -... -
Page 24: Static Threshold
0. Setting method: Click the "Still Threshold" option in the configuration bar of the PC software to set the threshold. The module default is 0.122°/ s. BWT61 | manual v0707 | http://wiki.wit-motion.com/english - 24 -... -
Page 25: 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 5Hz. The waveform is very steady. BWT61 | manual v0707 | http://wiki.wit-motion.com/english - 25 -... - Page 26 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. BWT61 | manual v0707 | http://wiki.wit-motion.com/english - 26 -...
