The Megger Ground Resistance Tester DET2/3 is a high-performance instrument designed for measuring earth electrode resistance and soil resistivity. Here is an overview of its capabilities:

Key Features

High-resolution Measurement

Features a single fully-automatic range from 0.01Ω to 20kΩ, with an accuracy of ±0.5% and a maximum resolution of 1mΩ, ideal for large-scale ground systems.

Diverse Test Modes

Supports 2-pole, 3-pole, and 4-pole resistance tests, as well as 3-pole and 4-pole ART resistance measurements (range: 0.01Ω to 10kΩ), non-electrode (stakeless) resistance measurements (range: 0.01Ω to 10kΩ), leakage current measurements (range: 0.00A to 2.00A), and various continuity measurements and bonding tests.

Automatic Frequency Selection

Scans for frequencies with the lowest noise level and conducts tests at that frequency. The selected test current frequency, test current level, and enhanced filtering options are stored in memory.

Powerful Diagnostic Function

Provides a real-time trace of measurements, graphically showing the amount of noise from the system under test—a highly useful diagnostic tool for professional ground test engineers.

Large-screen Display

Equipped with a 4.3-inch color graphic display that clearly shows readings and displays noise levels graphically.

Convenient Data Storage & Transfer

Features a large-capacity internal memory that stores up to 5,000 records and 900,000 data points. Data can be downloaded to a PC running PowerDB software via USB.

Excellent Protection Performance

Adopts a double-shell design, featuring a tough outer shell to prevent collisions and an inner fire-retardant shell. Protection level is IP65, adapting to harsh environments.
