Fluke 1630-2 FC Earth Ground Tester

Fluke 1630-2 FC Earth Ground Clamp

The Fluke 1630-2 FC is a stakeless earth ground clamp that measures earth ground loop resistance on multi-earthed systems without driving a single test stake. Clamp the dual jaw around the earth conductor or rod, and the instrument injects a signal and reads the resulting ground loop resistance. That means you can test inside buildings, on power pylons and anywhere there is no soil for auxiliary stakes. It is the fast, safe way to check an earthing system where disconnecting parallel earths is not an option.

As an authorised Fluke distributor, Powerpoint Engineering supplies the 1630-2 FC to electricians, utilities and industrial maintenance teams across Ireland. The FC suffix marks Fluke Connect compatibility: each reading logs to the instrument and shares securely to the Fluke Connect app on your smartphone, so survey data leaves site with you rather than on a scrap of paper.

What the Fluke 1630-2 FC measures

• Stakeless earth ground loop resistance using the dual clamp jaw, with no need to disconnect parallel grounds
• Staked earth resistance using auxiliary stakes and rods where an isolated electrode test is required
• AC leakage current through the same jaw, with a selectable band-pass filter to separate genuine leakage current from noise
• Secure data logging and wireless sharing through the Fluke Connect system

Specifications

Where the Fluke 1630-2 FC is used

The dual-clamp method makes this instrument the practical choice wherever staked testing is impractical or unsafe. Typical Irish applications include:

• Earthing checks inside buildings, substations and plant rooms where stakes cannot be driven
• Testing earth electrodes on power pylons, masts and street furniture
• Periodic earthing verification on multi-earthed systems without interrupting the installation
• Locating AC leakage current on earth conductors during system troubleshooting

If you only need staked electrode testing, the Fluke 1621 earth ground tester is the simpler entry model; the 1630-2 FC steps up with stakeless measurement, leakage current testing and Fluke Connect.

FAQs

What is stakeless earth ground testing?

Stakeless testing uses a dual-jaw clamp to measure earth ground loop resistance on a multi-earthed system, without driving auxiliary stakes or disconnecting the electrode. It is faster and safer than staked methods and works in places with no access to soil, such as inside buildings or on pylons.

Can the Fluke 1630-2 FC still perform staked tests?

Yes. With auxiliary stakes and rods it performs staked 3-pole and 4-pole earth resistance measurements for isolated electrode testing, so one instrument covers both the stakeless and traditional methods.

Does the Fluke 1630-2 FC need regular calibration?

Yes. Like any test instrument, it should be calibrated on a set interval to keep readings traceable and defensible. Our in-house laboratory calibrates and repairs Fluke earth testers and issues traceable certificates.
