Fluke 1630 Manuale di istruzioni
Technical Data
Fluke 1630
Earth Ground Clamp Meter
• A wide ground loop resistance range, from 0.025 Ωto1500 Ω, to
satisfy all requirements
• Large jaw opening of 35 mm (1.38 in) for tests on ground conductors
and/or equipotential bus bars
• Measurement of ground leakage current, from 0.2 mA to 1000 mA,
without needing to disconnect - ideal for system troubleshooting
• Wide ac current measurement range from 0.2 A to 30 A allows one
instrument for multiple applications
• Continuity loop test - quickly assess whether resistance is less than
40 Ω, with audible alarm
• User-defined HI / LO Alarm limits, for rapid measurement evaluation
•Handy “Display-Hold” button for capturing readings in
hard-to-reach places
•Time saving memory function automatically records and
stores measured values
•Automatic self calibration ensures correct measurement every time
The clamp-on ground testing technique used by
the Fluke 1630 simplifies ground loop testing and
enables non-intrusive leakage current measurement.
The compact and rugged design makes the Fluke
1630 easy to use in small places and harsh environ-
ments, while the “Display-Hold” and the continuity test-
ing with an audible alarm function, ensures convenience
in use. The novel technique means that earth ground
loop testing and continuity testing can be completed
without breaking the circuit.
Earth Ground loop resistance measurements

Stakeless testing system
The Fluke 1630 uses the Stakeless testing method,
which eliminates the need to disconnect parallel
ground rods and find suitable locations for
placing auxiliary ground stakes. This saves time
and enables users such as industrial and utility
electricians, and field service electricians and
contractors, to perform earth ground loop tests
in locations where it is not possible to use other
techniques, such as inside buildings or on power
pylons. With the Stakeless testing method, earth
ground stakes are no longer necessary. The Fluke
1630 Earth Ground Clamp is placed around the
earth ground rod or the connecting cable. A known
voltage is induced by one half of the clamp and
the current is measured by the other half. The
tester automatically determines the ground loop
resistance at this grounding connection.
Applications
•Earth Ground loop testing in various installations
- for example, high voltage pylons, buildings, cell
phone substations, RF transmitters, etc.
•Inspection of lightning protection systems
•Leakage current measurement
