1) Similar to DIN 16 086, reference conditions acc. to IEC 770, e.g.
temperature 15 °C … 35 °C; humidity 45 % … 75 %; air pressure 860 mbar … 1060 mbar
2) The adjustment time (also called actuating time, response time or adjustment period) is the time required by
the sensor to output the correct level (with max. 10% deviation) after a sudden level change.
3) Average emitted power (electromagnetic energy) per cm² received on an object directly in front of the
antenna. The received emitted power depends on the antenna version and the distance.
