"The H301B is a HiPot from Hipotronics. HiPot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use HiPot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. HiPot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device. Dielectric Testers, Insulation Testers, and Megohmmeters are similar to HiPot testers. Popular manufacturers include Biddle, Megger, Fluke, Associated Research, Quadtech, Instek, and Slaughter.","Additional Features:","The H301B AC\/DC HiPot and Megohmmeter is an accurate bench type instrument designed to perform insulation tests on all types of electrical system components, assemblies and apparatus. They are designed for AC dielectric tests, DC dielectric tests and insulation resistance measurements with direct megohmmeter readings at 500 V DC output.","These testers are popular in the laboratory envionment due to the highly sensitive DC current meter and easily accessible front panel controls. They are also popular in production applications due to the rugged construction and ease of use."
