Overview
This document provides information on earth or ground resistivity accessories designed for reliable and safe measurements. The accessories are user-friendly, universal, and compact, ensuring ease of use and compatibility with various instruments.

User-Friendly Features
- Simple Connections: Cables are color-coded to match the connecting terminals of the instruments, minimizing errors.
- Easy to Use: Handles on cable coils provide a firm grip during installation and can be removed for storage.

Universal Compatibility
- The kits are compatible with all instruments due to the 4 mm Ø banana jack/fork plug adapters.

Compact Design
- Carrying bags with separate compartments facilitate storage and transport.

Product References
- Various kits and accessories are available, including loop kits, earth kits, resistivity kits, and carrying bags, each with specific ordering references.

Earth Resistance Measurement
- Earth kits are used to measure the resistance of existing earth probes using the 3P method with two auxiliary rods.
- Example: Measurement of earth resistance RE by the “62 %” method.

Measurement of Ground Resistivity
- Earth and resistivity kits are used for measuring earth and ground resistivity, requiring four rods for calculation methods like Wenner’s method.
- The distance between rods affects the depth of resistivity measurement.

Kit Components
- Earth kits include coils of red and blue cables, a flat spool of green cable, T-shaped rods, a hammer, and adapters.
- Earth and resistivity kits include additional coils of black and green cables, with variations in carrying bag types based on kit length.
