Fluke 1630
Earth Ground Clamp Meter
Earth Ground loop resistance measurements for commercial, industrial, and utility applications
The clamp-on ground testing technique used by the Fluke 1630 simplifies ground loop testing and enables non-intrusive leakage current measurement. The compact and rugged design makes the Fluke 1630 easy to use in small places and harsh environ­ments, while the “Display-Hold” and the continuity test­ing with an audible alarm function, ensures convenience in use. The novel technique means that earth ground loop testing and continuity testing can be completed without breaking the circuit.
Technical Data
•  A wide ground loop resistance range, from 0.025 Ω to1500 Ω, to 
satisfy all requirements
•  Large jaw opening of 35 mm (1.38 in) for tests on ground conductors 
and/or equipotential bus bars
•  Measurement of ground leakage current, from 0.2 mA to 1000 mA, 
•  Wide ac current measurement range from 0.2 A to 30 A allows one 
instrument for multiple applications
•  Continuity loop test - quickly assess whether resistance is less than 
40 Ω, with audible alarm
•  User-defined HI / LO Alarm limits, for rapid measurement evaluation

Stakeless testing system
Applications
The Fluke 1630 uses the Stakeless testing method,  which eliminates the need to disconnect parallel  ground rods and find suitable locations for  placing auxiliary ground stakes. This saves time  and enables users such as industrial and utility  electricians, and field service electricians and  contractors, to perform earth ground loop tests 
  Earth Ground loop testing in various installations 
- for example, high voltage pylons, buildings, cell  phone substations, RF transmitters, etc.
  Inspection of lightning protection systems
  Leakage current measurement
in locations where it is not possible to use other  techniques, such as inside buildings or on power  pylons.  With the Stakeless testing method, earth  ground stakes are no longer necessary.  The Fluke  1630 Earth Ground Clamp is placed around the  earth ground rod or the connecting cable. A known  voltage is induced by one half of the clamp and  the current is measured by the other half. The  tester automatically determines the ground loop 
resistance at this grounding connection.
