The AEMC Model 6471 is a portable multi-function ground resistance tester measuring ground resistance with 2 clamps (no auxiliary rods), bond/connection resistance (2-pole and 4-pole Kelvin sensing), ground resistance (3-pole or 4-pole), ground coupling resistance, selective ground resistance, and soil resistivity (Wenner or Schlumberger).

Auto-ranging from 0.01 to 99.99 kΩ with adjustable test frequency (41-513 Hz) provides accurate readings in electrically noisy environments. The tester stores 512 test results and includes DataView software for data analysis. It is CAT IV rated to 50 V and overvoltage protected to >250 V AC. Comes with two SR182 current probes, NiMH battery, USB cable, and software.
