TECHNICAL DATA

Fluke 1630-2 FC
Earth Ground Clamp

AC LEAKAGE CURRENT
MEASUREMENT

Identify ac leakage currents without dis­connecting the earth ground stake from
the grounding system–ideal for system
troubleshooting.

Stakeless earth ground loop and ac leakage current
clamp for fast, safe indoor/outdoor earth ground
resistance and ac leakage current tests.

Test the grounding components of equipment in hard-to-reach
spaces, including areas that are indoors or fully paved and do not
permit driving auxiliary test stakes. Stay on line—identify ground
loop resistance without the need to disconnect then reconnect the
earth electrode from the system.

The Fluke 1630-2 FC Stakeless Earth Ground Clamp is the kind of
high-quality, rugged tool you expect from Fluke. Heavy-duty clamp
jaw stays in alignment and in calibration even in every day,
on-the-job industrial environments.

Stakeless measurement

The 1630-2 FC clamp measures earth ground loop resistances
for multi-grounded systems using the dual-clamp jaw. This test
technique eliminates the dangerous and time-consuming activity
of disconnecting parallel grounds, as well as the process of finding
suitable locations for auxiliary test stakes. You can also perform
ground tests in places that were previously difficult: inside build­ings, on power pylons or anywhere you don’t have access to soil to
place auxiliary test stakes.

With this test method, a two-process measurement is made around
the earth ground wire or bus bar using the specially-designed jaw
of the 1630-2 FC clamp. Auxiliary test stakes are not used at all.
A known voltage is induced by the source in the clamp, and the
current is measured by the sensor in the clamp. The tester auto­matically determines the earth loop resistance for this section of
the earthing system.

RUGGED

Heavy-duty clamp jaw stays in alignment
and in calibration even in every day, on­the-job industrial environments.

LOGGING MEASUREMENTS

The ear th ground clamp saves time by
automatically recording data at pre-set
intervals and saves up to 32,760 mea­surements in memory at the set logging
interval. Saves time by recording and stor­ing measured values.

ALARM THRESHOLD

User-defined high/low alarm limits, for rapid
measurement evaluation.

BAND-PASS FILTER

Selectable band-pass filter function
removes unwanted noise from the ac leak­age current measurement.

FLUKE CONNECT© WIRELESS SYSTEM

The 1630-2 FC suppor ts the Fluke Connect© Wireless System
(may not be available in all regions). Fluke Connect© wirelessly
connects the clamp with an app on your smartphone or tablet.
The app shows the ground resistance measurements on your
smartphone or tablet display. You can save these measurements,
GPS location from your phone and images to Fluke Connect Cloud
storage and share with your team.
