The 3765 is a Hipot from Associated Research. 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.
