The AEMC Instruments Model 6472 is a multi-function digital ground resistance tester that is designed to measure a variety of grounding parameters, including:
- Bond resistance
- Ground resistance (with and without clamps)
- Soil resistivity
- Earth coupling
- Step & touch potential
It is a portable instrument that is rugged and easy to use, making it ideal for use in a variety of applications, including:
- Electrical grounding systems
- Lightning protection systems
- Telecommunications grounding systems
- Power transmission and distribution systems
The Model 6472 has a number of features that make it a versatile and easy-to-use ground resistance tester, including:
- Auto-ranging, which automatically selects the optimum measurement range, test frequency, and test current
- Up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC via DataView® software
- Rugged construction that meets or exceeds mechanical and safety specifications for shock, vibration, and drop tests per IEC standards
- Adjustable test frequency provides for rejection of high levels of interference, allowing it to be used under difficult conditions such as high stray currents that affect accuracy
