Introduction The WT61C is a multi-sensor device detecting acceleration, angular velocity and angle . 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.
For proper instrument grounding: use WITMOTION with its original factory-made cable or accessories. For secondary developing project or integration: use WITMOTION with its compiled sample code. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 6 -...
WT61C Playlist 2.1.1 Serial Connection Step 1. Connect the sensor with a serial converter PIN Connection: VCC - TX - RX - GND - GND (When connecting with computer, VCC-5V is recommended.) WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 7 -...

The module needs to be calibrated before using it. Every instrument needs to be calibrated for the first use. Customers need to calibrate the accelerometer and magnetometer, the gyro will calibrate automatically. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 13 -...
Before calibration, there will be different degrees of bias error. After calibration, the measurement will be accurate. Methods: 1. Firstly keep the module horizontally stationary, then click “Acceleration Calibration” in the “Config” of the software. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 14 -...

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. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 15 -...
When the module is powered on, the Z axis will automatically return to 0. Step 1: Calibration methods as follow: firstly keep the module static, click the “Config” open the configuration bar and then click “Reset Z-axis Angle” option WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 16 -...
Page 17
The angle of the Z axis will return back to 0 degree in the module data bar. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 17 -...
Note: After the change, the module no longer outputs data at the original baud rate, and the data will be output only when the baud rate that has been changed is selected on the PC software again. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 18 -...
Method are as follows: Click“Record”and“Begin”will save the data as a TXT file.The saved file is in the directory of the upper computer program Data.tsv: the beginning of the file has the value corresponding to the data. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 19 -...

It is highly recommended that data can be pasted to a Excel file. In this way, all data will be shown in order. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 20 -...
Recorded data playback method: Step 1: Disconnect the sensor Step 2: Click “File” Button and then click “Load” WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 21 -...

Step 4: Click “Run” and the Binary file will be playback When playback, the rate can be editable. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 23 -...
Wake up: The module enters the working state from the standby state. The module defaults to a working state, in the“Config”of the software, click “Sleep”option to enter the sleep state, click“Sleep”again to release sleep. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 24 -...
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 WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 25 -...
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. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 26 -...
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. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 27 -...
Page 28
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. WT61C TTL| manual v0527 | http://wiki.wit-motion.com/english - 28 -...
