AEMC 3620 Ground Resistance Meter

AEMC 3620 Kits

• AEMC 3711 & AEMC 3731 Clamp-On Ground Resistance Testers (Cat.# 2117.60 & 2117.61)
  The Clamp-on Ground Resistance Tester Model 3711 measures ground rod and small grid resistance through any season, without the use of auxiliary ground rods.
  
  
  Check Resistance on Single and Multiple Rods or Grids
  Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The Model 3711 and 3731 simply clamps around the ground conductor or rod and measures the resistance to ground. By performing measurements on intact 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 3731 additionally provides memory and alarm features.

  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
  Alarm function with adjustable set point and buzzer for quick field checks (AEMC 3731)
  Memory function to store 99 field measurements for later retrieval (AEMC 3731)
  CE Mark and UL approved
  Rugged Lexan head and body construction resists breakage
  Alarm settings and stored memory information saved during shutdown

  
  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
