Earth Resistance
Measurement.

Earth resistance testing is essential for verifying the integrity of grounding systems in electrical installations. A reliable ground ensures safety during fault conditions, prevents equipment damage, and supports surge protection systems. The Fluke 1630-2 FC Earth Ground Clamp Meter simplifies this critical task—enabling fast, safe, and accurate ground testing without disconnecting system earths.

What Is Earth Resistance Measurement?

Earth resistance is the resistance encountered by current as it travels from an electrical installation into the earth. High resistance indicates poor grounding, which can result in:

• Shock hazards

• Equipment malfunction

• Inadequate lightning protection

• Poor signal reference for sensitive electronics

Traditionally, measuring earth resistance required driving auxiliary stakes and disconnecting the earth connection—but not with the Fluke 1630-2 FC.

Fluke 1630-2 FC: Key Features

• Stakeless Ground Testing
  Measures ground loop resistance by clamping around the ground conductor—no earth rod needed.

• Leakage Current Measurement
  Detects and logs low-level leakage currents (0.2 mA to 30 A), helpful for ground system diagnostics and safety verification.

• Fluke Connect® Wireless Integration
  Send data to your phone or PC via Bluetooth for logging, live trending, and instant reporting.

• Data Logging & Storage
  Stores up to 32,760 measurements for long-term trending and time-based analysis.

• Rugged Design
  Built for industrial use with CAT IV 600 V safety rating and durable construction for harsh environments.

The Fluke 1630-2 FC Earth Ground Clamp Meter takes the complexity out of ground resistance testing. With no stakes, no disconnection, and no interruptions, it’s the fastest and safest way to verify ground system health—perfect for routine maintenance, safety audits, and commissioning across industrial, commercial, and utility settings.
