UNI-T Digital Earth Tester – Earth 40kΩ Soil 40kΩ Ust 50V DC

Earth Resistance Measurement:

• Measures ground resistance up to 40kΩ

• Supports 2-wire, 3-wire, and 4-wire (Kelvin) test methods for flexible use across different site conditions

• High accuracy with selectable test frequencies (94Hz / 128Hz) to minimize interference

Soil Resistivity Testing:

• Calculates soil resistivity using the Wenner method with 4 test probes

• Supports testing for grounding system design and soil analysis

Disturbance Voltage & Frequency Detection:

• Measures external disturbance voltage (Ust) up to 50V AC/DC and frequency up to 500Hz

• Automatically blocks testing when unsafe interference is detected

Compensation Function:

• RK compensation function ensures stable readings even under varying conditions

Data Storage & Display:

• Stores up to 20 sets of test results for later recall

• Large backlit LCD display shows real-time values clearly, even in low-light environments

• Features Data Hold, low battery warning, and auto power-off
