Earth Ground Resistance Tester Kit The 382252 test kit includes everything needed to measure earth ground in three separate ranges – from 20 to 2000 ohms with ±2% accuracy. The kit features a large dual display with backlight, Test Hold function for easy operation, Automatic Zero adjustment, Auto Power off, Overrange, and low battery indication. The 382252 uses a Key Benefits The integrity of earth ground connections is of utmost importance; not only for safety but for efficiency and proper operation of electrical systems in buildings, plants, and sub-stations. A good earth ground connection ensures that, in the event of an electrical malfunction, current can be safely and harmlessly routed to ground. Poor earth ground connections can cause personnel injury and equipment damage when current is blocked from moving to earth ground. OSHA Safety Specifications require such ground resistance measurements. Earth Ground Resistance testers are a great way to ensure compliance and proper operation of electrical systems.
