Item category Ground Resistance Testers 3-4 Pole
|
 Features Measures ground resistance (2- and 3-point) and soil resistivity (4-point) Step voltage tests and touch potential measurements High 20 kiloOhm range for soil resistivity measurements Fall-of-potential method Selectable: three test currents and five resistance ranges Measures very low resistance on large grounding systems and grids May be used for continuity tests on bonding The Digital Ground Resistance Tester Model 4500 is designed for measuring very low resistance on large grounding systems, such as ground grids and ground mats. It rejects high levels of interference voltages at DC or 60 Hz and its harmonics, and can be used under difficult conditions such as high stray currents or excessive auxilliary electrode resistance.
