Fluke 1621 Basic Earth Ground Tester<br />

Earth ground tester for resistance measurement<br />

The Fluke 1621 Earth Ground Tester is a rugged, easy-touse<br />

tester for three-pole ground resistance measurements<br />

and two-pole ac resistance measurements.<br />

Earth ground resistance is measured by installing<br />

earth ground test electrodes, and testing with the Fluke<br />

1621. Earth ground resistance measurements are used<br />

to ensure safe operation and reduce power quality<br />

problems. With a simple user interface and intuitive<br />

functionality, the large, clear LCD display provides high<br />

visibility results in daylight or poor lighting conditions.<br />

The 1621 is lightweight making it ideal to test for<br />

lightning protection levels and periodic check-ups during<br />

routine maintenance.<br />

• Three-pole earth resistance measurements<br />

Fluke 1630 Earth Ground<br />

Clamp Meter<br />

The Fluke 1630 Earth Ground Clamp Meter is able to measure<br />

ground loop resistances—using the stakeless testing method.<br />

This test technique eliminates the dangerous, and time consuming<br />

activity, of disconnecting parallel grounds, as well as<br />

the process of finding suitable locations for auxiliary ground<br />

stakes. You can also perform earth ground tests in places you<br />

have not considered before: inside buildings, on power pylons<br />

or anywhere you don’t have access to soil.<br />

With the stakeless testing method, the Fluke 1630 Earth<br />

Ground Clamp Meter is placed around the earth ground rod or<br />

the connecting cable. No earth ground stakes are used at all.<br />

A known voltage is induced by one half of the clamp and the<br />

current is measured by the other half. The tester automatically<br />

determines the ground loop resistance at this grounding<br />

connection. Gone are the days of spending time placing and<br />

connecting stakes for each earth ground rod on your system—a<br />

major time saver.<br />

• Quick and easy use—no earth ground stakes are necessary<br />

• Large, 35 mm (1.35 in) jaw opening<br />

• Measures ground resistance from 0.025 Ω to 1500 Ω<br />

• Measures ground leakage current from 0.2 mA to 30 A<br />

• High and low alarming<br />

• Automatic self calibration<br />

• Rugged carrying case and resistance check loop included<br />

• Two-year warranty<br />
