Q1:The sensor reading is abnormally large or unchanged.
A1:
1. Check whether the power supply of your sensor is stable;
2. Please check whether the direction of the electrode patch is consistent with the direction of the muscle (as shown below), and the electrode patch should be tied to a large area of exposed skin.
3. Try pulling out the connector of the sensor electrode to see if the reading is normal.
