The Rod-L AC Hipot Testers are completely self-contained, rugged, high voltage potential test instruments designed for laboratory and production testing environments. They also have safety ground continuity test capability for performance of dielectric withstand tests in accordance with applicable UL, CSA, IEC, FCC, BABT, and other standards. The AV in the designation refers to units that test and display total current, while the BV units test and display total current as well as the resistive part of the AC current.
