The Fluke 1623-2 and 1625-2 GEO Earth Ground Testers offer automated data collection and storage, with download capabilities via a USB port, eliminating data entry and recording errors. The higher end 1625-2 features Automatic Frequency Control (AFC) which identifies interference and chooses measurement frequency to provide an accurate earth ground value. Optional colour coded wires provide easier identification and deploying of wire reels and stakes, thus offering faster setup. 

A lack of proper grounding also increases the risk of equipment failure. Without an effective grounding system, electrical devices are subject to instrumentation errors, harmonic distortion issues, power factor problems and a host of possible intermittent dilemmas. Studies show that as much as 25% of power quality problems are related to poor grounding. The new IP56-rated Fluke 1623-2 and 1652-2 GEO Earth Ground Testers can perform all four types of earth ground measurement:

• 3- and 4-pole Fall of Potential (using stakes)

• 4-pole Soil Resistivity testing (using stakes)

• Selective testing (using 1 clamp and stakes)

• Stakeless testing (using 2 clamps only)

The testers are easy to use. For each test, the tester indicates which stakes or clamps need to be connected and the large rotary switch can be used even with a gloved hand. Other features on the Fluke 1625-2 include R* measurement, which calculates earth ground impedance at 55Hz.

Available also as complete kits, these come with the 1623-2 or 1625-2 tester, test leads, 4 earth ground stakes, 3 cable reels with wire, 2 clamps, batteries, and manual – all inside a professional Fluke carrying case. Plant & Asset Management Stand P106
