Earth resistance tester GEO Basic model

Fluke Earth Ground Tester

Product Overview

The Fluke 1623-2 GEO Earth Ground Tester is an earth ground tester designed to measure earth ground resistance and earth loop impedances using clamps, ground stakes, or a combination of these. The instrument supports 3- and 4-pole Fall-of-Potential measurements as well as 4-pole soil resistivity measurements. The Fluke 1623-2 includes internal memory and USB access for data readout.

Features and Measurement Methods

• 3- and 4-pole Fall-of-Potential measurements (earth ground resistance with stakes)
• 4-pole soil resistivity measurement
• Selective measurement with one current clamp
• Stakeless measurement with two clamps
• Internal memory for up to 1500 measurement records, accessible via USB
• Robust housing with IP56 rating for outdoor use

Typical Applications

• Stakeless measurements where access to ground is not possible — for example, inside buildings or in places where ground stakes cannot be placed (described in manufacturer documentation)
• Selective ground conductor/ground rod test using one current clamp

Use of Documentation

Refer to the manufacturer's technical documentation for details on measurement principles, measurement ranges, and limitations. See manufacturer's datasheet
