Ground Resistance Tester, 4 Pole
The Amblyonix 5004 is designed to measure the resistance of grounding electrodes or grids, utilizing the fall-of-potential test method. The Model 5004 is perfectly suited to perform soil-resistivity measurements, touch-potential measurements, touch/step potential measurements, and display earth-voltage readings. Phase-locked loop and switched-filter design allow for smooth operation even in electrically noisy environments. Standard features include a rugged aluminum alloy case, three resistance ranges, an earth voltage measurement function, four-pole terminal connections, line or battery power capability, and a direct reading digital display.
The unit is supplied with a power cord for charging internal batteries, auxiliary electrodes, test cables and connectors for performing various types of tests, and a manual.
