AEMC 3711 Clamp-On Ground Resistance Tester

The AEMC 3711 measures ground rod and grid resistance in any environment without the use of auxiliary ground rods. Clamp-on ground resistance testers are used on multi-grounded systems without disconnecting the ground under test. The 3711 simply clamp around the ground conductor or rod and measures the resistance to ground fast and accurately.

By performing measurements on installed ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.

The AEMC 3711 includes a current measurement function. The probe's high sensitivity enables measurement of leakage current flowing to ground or circulating in ground loops down to 1 mA as well as neutral and phase currents to 30 Arms. This feature provides additional information, which is vital in distribution ground networks carrying higher levels of noise and harmonics, that affect power quality.

Applications:

• Measure electrical ground rod and grid resistance
• Use on multi-grounded systems without disconnecting the ground rod under test
• Measure resistance and continuity of grounding loops around pads and buildings
• Measure leakage current flowing to ground or circulating in ground systems
• Conduct field surveys and retrieve and analyze readings at a later time
• Use on cell towers and telecommunication sites
• Use on pools, spas and other consumer installations

Features:

• Simple and fast clamp-on operation - no leads, no auxiliary rods or spacing requirements. No need to disconnect neutral service
• Direct reading of ground resistance from 0.01Ω to 1200Ω
• Direct reading of continuity and ground loop resistance
• Direct reading of ground leakage or phase current from 1mA to 30Arms
• Jaw design with large 1.25" (32mm) window - accommodates up to 1000MCM cables
• Auto-off for power management
• CE Mark and UL approved
• Rugged Lexan head and body construction resists breakage
• Patented design
