Earth ground tester kit

The Fluke 1625/1623 earth ground testers can perform all four types of earth ground measurement.

Specifically, the testers are able to measure earth ground loop resistances using only clamps — called Stakeless testing. This method doesn’t require the use of earth ground stakes or the disconnection of ground rods.

Features include:

• 3- and 4-pole Fall of Potential, earth resistance loop testing;
• 4-pole Soil Resistivity testing;
• Selective earth ground rod testing using 1 clamp;
• Stakeless earth ground rod testing using 2 clamps;
• IP56 rated for outdoor use;
• Automatic Frequency Control (AFC) — identifies existing interference and chooses a measurement frequency to minimise its effect, providing a more accurate earth ground value;
• R* measurement — calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see;
• Adjustable limits — for quick test result verification.
