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.
