2.6.2.2 Recommendations for choosing the type of measurement
1. When choosing the type of measurement, check out the size of a tested
area. If the area is limited in size (for example, one of its directions does not exceed
3 m or buildings are located within a few meters), local measurement performed by
positioning the detector at the height of 10 cm is recommended.
