Amperimeter SEN0211 and SCT013

Good morning.
I am trying to measure the power of an electrical device. I use an SCT013 with a SEN0211 ( https://www.tme.com/us/es/details/df-sen0211/otros-sensores/dfrobot/sen0211/ )
I copied an example and tried it. It doesn't measure correctly. The truth is that I don't really know what I'm doing. Does anyone know or have an example that I can follow to correctly measure the power? I'm attaching the code I'm using and it doesn't measure correctly.
I have tried it with different Arduinos, please note:
For Arduino UNO, Leonardo and mega2560, etc. change VREF to 5
For Arduino Zero, Due, MKR Family, ESP32, etc. 3V3 controllers, change VREF to 3.3
Thanks.

//Potencia
const int ACPin = A3;         //set arduino signal read pin
#define ACTectionRange 20;    //set Non-invasive AC Current Sensor tection range (5A,10A,20A)

// VREF: Analog reference
// For Arduino UNO, Leonardo and mega2560, etc. change VREF to 5
// For Arduino Zero, Due, MKR Family, ESP32, etc. 3V3 controllers, change VREF to 3.3
#define VREF 3.3

 Serial.println(" W");
 delay(3000);
 }

 float ACCurrtntValue = 0;
 float peakVoltage = 0;  
 float voltageVirtualValue = 0;  //Vrms
 for (int i = 0; i < 6; i++)
   {
   peakVoltage += analogRead(ACPin);   //read peak voltage
   delay(1);
   }
 peakVoltage = peakVoltage / 6;   
 
 voltageVirtualValue = peakVoltage * 0.707;    //change the peak voltage to the Virtual Value of voltage

 /*The circuit is amplified by 2 times, so it is divided by 2.*/
 voltageVirtualValue = (voltageVirtualValue / 1024 * VREF ) / 2;  

 ACCurrtntValue = voltageVirtualValue * ACTectionRange;

 Serial.print("VoltageVirtual = "); Serial.println(voltageVirtualValue);
