Description
|
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 60Hz and its harmonics, and can be used under difficult conditions such as high stray currents or excessive auxiliary electrode resistance.
