Ground TestingGround Test EquipmentApplicationsERICO ® Inc. offers a complete range of Ground/Earth ResistanceTesters. The units are lightweight and portable for ease of use in thefield. Their robust design and splash-proof construction help themwithstand extreme conditions. The units’ large LCD display showsrequired test connections and features a complete automatic testsequence for selected operations.Three units are offered in the range. The Handy Earth Tester EST101is a small handheld unit that can complete the 2-pole resistancemeasurement and the 3-pole earthing resistance measurement, aswell as a ground to neutral impedance test.The Earth System Tester EST201 is a slightly larger yet still portableunit and adds the capability to perform 4-pole resistancemeasurements for the determination of soil resistivity.The Universal Earth System Tester EST301 provides the samemeasurement capabilities as the EST201 in addition to clamp-onselective and stakeless measurement capabilities. Clamp-onselective provides the ability to measure the resistance ofinterlinked ground/earth systems without the influence fromparallel ground paths. This capability is ideal for systems which arepermanently bonded using CADWELD ® exothermically weldedconnections.The ESTREELKIT500 is a set of two 500’ long test leads on heavydutyreels, ideal for three point fall-of-potential measurements atlarge sites.No matter what the application, there is sure to be a Ground Testersuited to fit your many diverse ground/earth measuring needs.EST101 – Handy Ground Tester• 2 pole resistance and 3 pole ground/earth resistance measurements@128Hz• GTN adapter cable provides Ground to Neutral impedance tests on livecircuits per IEEE Std. 1100-1992• Provided as a complete kit which includes required cables, leads, groundstakes, carrying case and carry belt• Large high contrast liquid crystal display with easy to understandgraphics and symbols• Microprocessor controlled to automate the measuring process• Lightweight and portable for ease of use in the field• Automatic recognition of connection of measuring leads and itsconnections to earthEST201 – Ground System Tester• 2 pole resistance and 3 pole ground/earth resistance measurements@94/105/111/128Hz• 4 pole resistance measurement for determining soil resistivity• Provided as a complete kit which includes required cables, leads, groundstakes, carrying case and Grounding Tutorial book• Large high contrast liquid crystal display with easy to understandgraphics and symbols• Microprocessor controlled to automate the measuring process• Lightweight and portable for ease of use in the field• Automatic recognition of connection of measuring leads and itsconnections to earthPh: 1-800-677-9089www.erico.com67
