The Meco 4680BLC Digital Earth / Ground Resistance & Leakage Current Tester is an advanced Clamp-On Non-Contact Earth Testing Instrument developed for professional electrical maintenance and grounding system analysis. It allows technicians to measure earth resistance and leakage current quickly without disconnecting the circuit or installing auxiliary earth rods, making it highly effective for field testing and preventive maintenance applications.
The instrument uses a long elliptical clamp jaw design that allows easy measurement on both flat earthing strips and round grounding conductors. The clamp design helps save time during inspection by eliminating the need for traditional earth electrode methods and avoiding unnecessary shutdowns of electrical installations.
The Meco 4680BLC provides accurate measurement of:
Ground Resistance: 0.01Ω to 1000Ω
Leakage Current: 0.5mA to 30.00A AC (TRMS Mode)
It is suitable for testing:
Industrial grounding systems
Electrical substations
Transmission towers
Distribution feeders
Lightning arrestor systems
Telecom towers
Power generation and distribution installations
Electrical appliances and safety systems
The tester supports earthing strips and conductors up to approximately 65mm × 32mm, making it suitable for a wide range of industrial earthing arrangements. The 4-digit 9999 count LCD display provides clear measurement readings, while the auto-ranging feature automatically selects the appropriate measuring range for efficient operation.
The Meco 4680BLC includes several advanced functions for professional testing:
Data Storage Memory – Stores measurement readings for future reference.
Data Hold Function – Freezes displayed values for easy recording.
Noise Signal Indication – Helps identify interference during testing.
Continuity Loop Test – Provides additional grounding verification.
Configurable Alarm Function – Allows setting resistance and current alarm limits.
Auto Power Off – Helps conserve battery life.
The tester is designed for field engineers, electrical contractors, maintenance professionals, and safety inspectors. It operates on 4 × 1.5V AA batteries and is supplied with a resistance verification plate, carrying bag, batteries, and instruction manual for convenient operation.
