2 Description of Instrument
The compliance with the actual EMC-regulations is documented by the at-
tached CE-sign.
The clamp-on ground resistance tester enables the user to measure ground
resistance of the ground rod without the use of auxiliary ground rods.
Clamp-on ground resistance testers are used in multi-grounded systems
without disconnecting the ground under test.
Applications:
•
earth resistance of various installations (high voltage pylons, buildings,
cell phone substations, RF transmitters etc.)
•
inspection of lightning protection systems
