Kako instrument meri malu omsku vrednost ima primenu i kod merenja otpornika vrednosti ispod 1 om kao i šantova, kod merenja ESR elektrolintskih kondenzatora sa visokom preciznošću.
Isto tako instrument ima primenu kod merenja Rds mosfetova da bi se utvrdilo njegovo stanje pre upotrebe.Za takvo ispitivanje potrebno je dovesti napon od 10V i može se uraditi merenje kao na slici.
