Ground Resistance Tester
Ground resistance testers are used for
the design and testing of grounding systems used by power companies, industrial
plants, CATV and telephone companies, and for antenna systems.

 |
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 easy-to-read LCD
|
Display includes indicators for
excess stray current, high stray voltage, high auxiliary rod
resistance and fault connection
|
Rugged dustproof and rainproof field
case
|
Can be used for continuity tests on
bonding
|
Battery (rechargeable 110V/220V)
powered or external 12VDC
