FALL-OF-POTENTIAL TESTER |
- Measures
ground resistance (2 and 3 points) and soil
resistivity (4 points)
- Step voltage tests and touch potential measurements
- Selectable : three test currents and five
resistance ranges
- Measure very low resistance on large grounding
systems and grid
- High test current also enables geological
surveys
- Large LCD display for easy reading
- Display includes indicators for excess stray
current, high auxiliary rod resistance, and
faulty connection
- Battery (rechargeable 110V/220V) powered or
external 12V DC
- Rugged dustproof and rainproof case
- May be used for continuity tests and bonding
