AEMC 2135.51 Ground Resistance Tester

Overview

The AEMC 2135.51 is a portable digital ground resistance tester designed to measure bond resistance, ground resistance (with and without clamps), soil resistivity, earth coupling, and step & touch potential. The instrument supports advanced testing modes including 4-pole fall-of-potential measurement, soil resistivity analysis, and compatibility with the GroundFlex® Adapter for power transmission tower testing.

Key Features

• Selectable test voltages of 10, 16, 32, and 60 volts for sensitive areas and poor soil conditions
• 4-Point fall-of-potential measurement for very low resistance with manual or automatic frequency selection
• 3-Point fall-of-potential and earth coupling measurement modes
• Automatic frequency scan from 40 to 513 Hz for accuracy in electrically noisy environments
• 2- and 4-wire DC resistance measurement (bond testing) with automatic polarity reversal
• 4-point soil resistivity measurement with Wenner or Schlumberger method selection
• Ground resistance measurement with 2 clamps without auxiliary rods
• Stores up to 512 complete test results in internal memory
• DataView® software for data storage, analysis, and report generation
• Optically isolated USB communication and rechargeable NiMH batteries

Applications

• Grounding system testing and maintenance
• Electrical safety compliance and bonding verification
• Soil resistivity analysis for grounding design
• Power transmission tower and pylon leg testing (with GroundFlex® adapter)
• Field measurement in electrically noisy environments
