Fluke 1630 Earth Ground Tester
Introduction:
The Fluke 1630 Earth Ground Clamp (hereafter called the “the Clamp”) is a hand-held battery-operated clamp that measures the ground resistance of a ground rod without using auxiliary ground rods. The Clamp can be used in multi-grounded systems without disconnecting the ground under test.
The Clamp can be used in the following applications:
- Earth resistance testing of high voltage pylons, buildings, cell phone substations and RF transmitters
- Inspection of lightning protection systems
Standard Accessories
The following standard accessories are provided with the Clamp:
- 9-V alkaline battery (type IEC 6F22, NEDA 1604 installed)
- Resistance test/check loop
- 1630 Users Manual
- Carrying Case
