Technical Data
Fluke 1630
Earth Ground Clamp Meter
• A wide ground loop resistance range, from 0.025 Ω to1500 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.
