Product Overview
This description is about the Fluke 1625-2 GEO Earth Ground Tester, an earth resistance instrument from Fluke designed for measuring earth loop and earth resistivity. The instrument supports both clamp-based measurements and traditional stake-based methods and is intended for field measurements with stored data and USB transfer.Features
- Supported measurement methods: 3- and 4-pole Fall-of-Potential, 4-pole earth resistivity, selective test with 1 clamp, and stakeless test with 2 clamps.
- Automatic Frequency Control (AFC) for interference identification and measurement frequency selection.
- R* measurement for calculating earth impedance at 55 Hz.
- Internal memory with space for up to 1500 measurement records and data access via USB port.
- IP56 rating for the instrument housing for outdoor use.
Typical Applications
- Measurement of earth loop resistance using clamps (stakeless measurement with two clamps).
- 3- and 4-pole Fall-of-Potential measurements using earth rods/stakes.
- 4-pole earth resistivity test using stakes and probe leads.
- Selective earth rod test with one clamp plus stakes.
