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 in locations where it is not possible to use other techniques, including 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.
A wide ground loop resistance range, from 0.025 O to1500 O, 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, without needing to disconnect - ideal for system troubleshooting
Wide ac current measurement range from 0.2 A to 30 A allows one instrument for multiple applications
User-defined HI / LO Alarm limits, for rapid measurement evaluation
Handy ‘ display hold’ button for capturing readings in hard-to-reach places
Time saving memory function automatically records and stores measured values
Automatic self calibration ensures correct measurement every time
Overload protection: 200 A
Carrying case and resistance test loop included
e 8 hours battery life ( continuous operation)
