M71 HT Instruments HiPot

The M71 is a HiPot from HT Instruments. 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.

The earth ground resistance tester M71 is an innovative model designed to perform earth ground resistance measurements with 2-wire and 3-wire with volt ampere method in compliance with international standards. A wide measurement range is available for measurements (up to 50kOhm) along with automatic compensation of disturbance voltages. The 2-wire measurement method (where auxiliary metal parts are available such as metal surfaces, water pipes, neutral conductors) is extremely important in civil environments where 3-wire method cannot be used due to logistic reasons. Thanks to its ergonomic design and electronic range knob it is capable of quickly carrying out any test.
