CT clamp : Wrong value's


create a setting like

with this configuration

# Example configuration entry
  - platform: ct_clamp
    sensor: adc_sensor
    name: "Measured Current"
    update_interval: 10s

  # Example source sensor
  - platform: adc
    pin: GPIO36
    id: adc_sensor
    attenuation: 11db

when i measure with my amp clamp i get

Esp : 1,42 A clamp : 0.3A
Esp : 1,95 A clamp : 4.4A
Esp : 1.95 A Clamp : 8.3A
