swSensorType return value = 4?

Hi, I have added measurement sensor. to a part and are trying to get the value from it in a macro.

But when running the macro I get a returnvalue that not exists in the documentation, code: Debug.Print swSensor.SensorType --> 4

The return value should be 2 according to the documentation. Anyone experiencing the same?, I am running SW2013sp2
