Na principu vzájemné indukce může měřit zemnicí odpory bez rozpojování zemnicích vodičů a bez pomocných elektrod, a to v uzemňovacích soustavách s více zemniči i s jedním zemničem. Na rozdíl od podobného přístroje UT276A+ má rozšířený rozsah měření odporů zemní smyčky až na 1200? a navíc umí měřit i unikající proudy zemní smyčkou v rozsahu 0,00mA až 20,0A.\u003cbr\u003eTester je navržen pro profesionální použití s odolností vůči nárazům, prachu a vlhkosti a je řízen mikroprocesorem pro přesnou identifikaci odporu uzemnění, včetně funkce rychlé filtrace rušivých signálů, s využitím pokročilých aritmetických metod. Je určen pro měření zemnicích soustav v elektrárnách, energetických a telekomunikačních rozvodech, ropných polích, počítačových místnostech, elektromechanických instalacích a při údržbě v průmyslových podnicích, všude, kde je používaná elektřina jako průmyslový zdroj energie, nebo kde je třeba kontrolovat zemnicí odpor hromosvodů. Přístroj měří odpor zemní smyčky od 0,01 ? do 1200 ? s rozlišením 0,001 ? a unikající proudy 0 až 20A, naměřené hodnoty se zobrazují na čtyřmístném podsvíceném displeji EBTN (světlé údaje na tmavém pozadí) a současně je možné hodnoty uložit do interní paměti (až 300 skupin hodnot).
