Advanced Ground Resistance Testing with ZXET3008

For electrical technicians and maintenance engineers, accurate ground resistance measurement is critical for system safety and compliance. The ZXET3008 Double Clamp Ground Resistance Tester represents a significant evolution in test equipment, combining multiple measurement methods and robust features tailored for demanding field conditions.

Versatile Measurement Capabilities
Unlike conventional ground testers limited to basic 3-pole or 4-pole methods, the ZXET3008 integrates five distinct techniques:

1.Traditional 2-wire, 3-wire, and 4-wire methods (0.000Ω-30kΩ)

2.Selective measurement (0.00Ω-3kΩ)

3.Double clamp method (0.01Ω-200Ω)

This versatility allows technicians to select the optimal method for different scenarios without carrying multiple instruments. The double clamp method is particularly valuable for testing grounded systems without disconnecting parallel connections, a limitation of standard ground testers.

Technical Superiority
The instrument achieves remarkable precision with 0.001Ω resolution in low resistance ranges and maintains ±2% accuracy across most measurement modes. Compared to earlier models that typically offer only 128Hz test frequency, the ZXET3008 incorporates automatic frequency selection (94Hz/105Hz/128Hz) with FFT and AFC technologies, significantly enhancing noise immunity in electrically noisy environments.

Key technical advantages include:

1.20mA test current for reliable measurements in high-resistance soils

2.Large φ52mm clamps accommodating substantial ground conductors

3.Comprehensive soil resistivity measurement using Wenner method

4.Integrated voltage (0-100V) and AC current measurement (0-600A)

Enhanced Field Performance
The tester addresses practical field challenges with features often missing in competitive models:

1.Visual and audible alerts for interference voltages above 5V

3.CT2 clamp direction indication when signal drops below 0.5mA

3.2000-data point storage with USB interface

4.IP54-rated rugged case supporting 200kg load capacity

Safety and Compliance
Meeting IEC61010-1 (CAT III 300V) and multiple international standards, the ZXET3008 provides overload protection up to AC 280V/3 seconds. This safety margin exceeds many comparable testers, crucial when working on potentially energized systems.

For technicians upgrading from basic ground resistance testers, the ZXET3008 offers a comprehensive solution that eliminates the need for separate devices for soil resistivity, ground voltage, and leakage current measurements. Its intelligent features and robust construction make it particularly suitable for utility, industrial, and lightning protection system applications where measurement reliability directly impacts system safety and performance.
