The Meco 4680SL Digital Earth / Ground Resistance Tester is an advanced clamp-on testing instrument designed for measuring earth resistance in electrical grounding systems without disconnecting the existing installation. Unlike traditional earth testers, this instrument eliminates the requirement for auxiliary electrodes, making testing faster, easier, and more convenient, especially in locations where conventional methods are difficult to perform.
The tester uses a non-contact clamp measurement technique that allows technicians to measure ground resistance simply by clamping the jaw around the earthing conductor. This saves considerable time during inspection and maintenance activities while avoiding power shutdowns. The long elliptical jaw design is suitable for both flat earthing strips and round conductors.
The Meco 4680SL provides a wide ground resistance measurement range of 0.01Ω to 500Ω with automatic range selection. It is suitable for testing:
Electrical earthing systems
Transmission towers
Lightning arrestors
Distribution towers and feeders
Telecommunication grounding systems
Industrial grounding installations
Power system safety applications
The instrument supports earthing strips up to 55mm width and round conductors up to 20mm diameter, making it suitable for various grounding configurations used in industrial and commercial installations.
The tester is equipped with a 4-digit 9999 counts LCD display with backlight, providing clear visibility of readings in different lighting conditions. The built-in memory function allows storage of up to 99 measurement sets, enabling technicians to record and review test results during inspection work.
The Meco 4680SL includes several useful operating functions:
Data Hold Function – Freezes the displayed reading for easy recording.
Data Storage Memory – Stores measurement values for later review.
Noise Signal Indication – Helps identify interference during measurement.
Continuity Loop Test – Provides additional grounding verification.
Auto Range Selection – Automatically selects the appropriate measuring range.
Auto Power Off – Conserves battery life.
The instrument operates on four 1.5V AA batteries and comes with a resistance verification plate for calibration checking. Its compact clamp design makes it suitable for field engineers, electricians, and maintenance professionals who require quick and reliable earth resistance measurements.
The Meco 4680SL is designed according to IEC/EN 61010-1 safety standards with CAT III 150V measurement category, providing reliable operation in professional electrical environments.
