PRESS RELEASE : Fluke 1630 Earth Ground Clamp Meter Measures Ground Loop Resistance without Stakes

EVERETT, Wash. - Fluke Corporation, the global leader in handheld electronic test and measurement technology, today announced the Fluke 1630 Earth Ground Clamp Meter, a rugged clamp meter with a wide 1.35 inch (35 mm) jaw opening that can measure earth ground loop resistances quickly and easily – even in locations where there is no access to soil.

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 field service, industrial maintenance and utility technicians to perform earth ground 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.

The Fluke 1630 measures ground resistance from 0.025 to 1500 ohms and True RMS current flow from 0.02 to 35 A; and enables non-intrusive leakage current measurements from 0.2 to 1000 mA. It features a HI/LO alarm function to help users quickly compare the measured value against upper and lower limits, a display-HOLD function, a recording function that allows storage of measured values, and automatic self calibration.

The Fluke 1630 Earth Ground Clamp Meter includes a resistance check loop and comes in a rugged carrying case. It is available immediately at a US list price of $1,349.
