Earth Ground Clamp utilizes the clamp-on ground testing technique which 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 environments, while the 'display hold' and continuity testing with an audible alarm function ensures convenience in use.

Ground Clamp Features:

• The Ground Testing technique means that earth ground loop testing and continuity testing can be completed without breaking the circuit
• The Stakeless testing method eliminates the need to disconnect parallel ground rods and find suitable locations for placing auxiliary ground stakes
• Earth ground loop tests can be performed in locations where it is not possible to use other techniques, including inside buildings or on power pylons - Earth ground stakes are no longer necessary
• A wide ground loop resistance range, from 0.025 Ω to 1500 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
