The Meco 4680BL Digital Earth / Ground Resistance Tester is an advanced Clamp-On Non-Contact Earth Resistance Measuring Instrument designed for professional electrical maintenance and grounding system inspection. It eliminates the requirement for traditional auxiliary earth electrodes, making earth resistance testing quicker, safer, and more convenient in difficult-to-access locations.
The instrument uses a long elliptical clamp jaw design that allows easy testing on both flat earthing strips and round grounding conductors. By simply clamping the tester around the earthing conductor, technicians can measure ground resistance without interrupting the electrical installation. This feature helps save significant time during preventive maintenance and electrical safety audits.
The Meco 4680BL provides a wide ground resistance measurement range of 0.01Ω to 1000Ω, making it suitable for various grounding applications including:
Industrial plant earthing systems
Electrical substations
Power distribution networks
Transmission towers
Lightning protection systems
Telecommunication grounding systems
Building electrical installations
The tester supports earthing strips up to 65mm × 32mm and round conductors up to 25mm diameter, allowing measurement of different types of grounding arrangements used in industrial and commercial applications.
The instrument is equipped with a large 4-digit 9999 count LCD display, providing clear and accurate measurement readings. The auto-ranging facility automatically selects the appropriate measurement range, reducing manual adjustments and improving testing efficiency.
The Meco 4680BL includes several advanced functions for professional use:
Data Storage Memory – Stores measurement readings for future reference.
Data Hold Function – Freezes displayed readings for easy recording.
Noise Signal Indication – Helps identify interference during measurement.
Continuity Loop Test – Provides additional grounding verification.
Auto Power Off – Conserves battery life during inactive periods.
The compact clamp design makes the tester suitable for field engineers, electrical contractors, maintenance teams, and safety professionals. It operates on 4 × 1.5V AA batteries and is supplied with a resistance verification plate, carrying bag, batteries, and instruction manual for convenient field operation.
