Field detector
Using the POC (Proof Of Communication) it is possible to simply and easily find the best-possible position for the transponder. This can prove to be particularly difficult with thermally coated, heated or infrared reflecting windscreens.
The POC acts precisely the same as a transponder (TPU 30xx or TPU 31xx), indicating the field strength at its position via the brightness of an LED. By moving the POC along a windscreen it is possible to ascertain the field strength at every position according to the brightness of the LED. That means finding the best-possible position for the transponder is fast, easy and straightforward.
