  SELECT THE RIGHT SOCKET FOR EACH SENSOR.

  Possible sockets for this sensor are:
  - XTR_SOCKET_B       _________
  - XTR_SOCKET_F      |---------|
                      | A  B  C |
                      |_D__E__F_|


  Example: 4-20mA sensor on socket A will be
  [Sensor Class]   [Sensor Name] [Selected socket]
  Industries_4_20  mySensor      (XTR_SOCKET_B);

  Refer to the technical guide for information about possible combinations.
