Emg sensors are not accurate

Hello everyone! I now have an emg sensor from steeper.group in my project:

https://www.steepergroup.com/prosthetics/upper-limb-prosthetics/battery-systems/electrodes-cables/

Used as a microcontroller arduno mega. There are no documents and libraries on the site how to write a code and wrote this code:

void setup() {
  Serial.begin(9600); 
}

void loop() {
  int sensorValue = analogRead(A1); 
  Serial.println(sensorValue); 
  delay(100); 
}

The problem is that if there is no signal from the muscle, then the Series shows the value of 900, if there is any signal, it will change a little. There are obstacles, can you please help me

That tells me the device is working properly! The EMG signal is AC and will show as above or below the 900 value. Are you using the company battery to power the device? Have you tried the maximum voltage of 16?
The company expects the user to know how to implement the device and is likely identical to similar EMG devices.
