AEMC 4500 Digital Earth Ground Tester
The Ground Resistance Tester Model 4500 is a heavy-duty instrument ideal for maintenance crews performing numerous tests. The Model 4500 rejects high levels of interference, and can be used under difficult conditions such as high stray currents that normally affect accuracy. The Model 4500 may be used to perform the following test:
Features:
• Fall-of-Potential method
• Measures ground resistance (2- and 3-Point) and soil resistivity (4-Point)
• Step voltage tests and touch potential measurements
• Selectable: three test currents and five resistance ranges
• Measures very low resistance on large grounding systems and grids
• High test current also enables geological surveys
• Large LCD display for easy reading
• Display includes indicators for excess stray current, high stray voltage, high auxiliary rod resistance and fault connection
• Includes AC Power cord, batteries, and manual
