Funkcionalnost
Merilniki lahko delujejo kot sprejemnik, repetitor ali kot merilne enote in direktno pošiljajo podatke spejemni enoti prek kratkih radisjkih valov - brezžično. Njihov domet je 400 m, za podaljšanje pa lahko uporabimo repetitor-merilnik, a ne več kot enega. En sprejemnik lahko komunicira z do 4032 merilnimi enotami. Prenos podatkov je samodejen glede na nastavitve. Vse enote lahko delujejo na baterijsko napajanje ali so prek adaptjerja vklopljeni v električno omrežje.
