## Summary description

Portable ground (earth) resistance tester Unit UT522 designed for accurate measurement of soil and grounding system resistance. Provides direct resistance readings for earth electrodes and grounding networks, with features for reliable contact testing, manual or automatic range selection, and clear digital display. Suitable for electricians, installers and maintenance teams for site verification and safety compliance checks.

## Long description

The Unit UT522 Ground Resistance Tester is a portable meter designed for direct measurement of earth/soil resistance and grounding systems. The instrument provides clear digital readings of resistance values for single earth electrodes and multi-point grounding networks. It features selectable manual or automatic range modes, a large display for easy reading, and reliable contact testing to ensure valid measurements during installation, commissioning and periodic inspection tasks.
Advantages
The tester delivers fast and repeatable resistance measurements with stable contact verification, reducing uncertainty during field testing. Its portability and battery operation make it practical for on-site verification and maintenance work. Simple range selection and an intuitive display minimize the need for extensive user training while maintaining accuracy needed for compliance checks and safety inspections.
Suitable for
Measuring earth electrode resistance for building grounding systems
Testing soil resistivity and ground network continuity at substations and installations
Periodic safety verification and installation commissioning by electricians and technicians
Field checks on lightning protection and surge grounding systems
Key specifications
Function: Earth/soil and grounding system resistance measurement
Display: Digital readout for resistance values
Range selection: Manual and automatic range modes
Contact testing: Dedicated verification to ensure valid probe connections
Power: Portable unit powered by internal batteries for field use
Form factor: Handheld, lightweight enclosure suitable for on-site measurement
How to use
Connect the test leads and auxiliary probes according to the grounding configuration being measured, ensuring secure contact with the electrode and earth stakes. Select the appropriate measurement mode (manual or automatic) and initiate the test to obtain the resistance reading on the digital display. Verify contact status indicated by the unit before recording results, and repeat measurements if required to confirm consistency. Observe standard safety practices when working near live equipment and de-energize circuits where necessary before performing earth resistance tests.
Usage recommendations
For reliable results, place auxiliary stakes at recommended distances from the electrode under test, avoid measuring in saturated or disturbed soil without noting conditions, and allow the instrument to stabilise between readings. Calibrate and maintain the tester as specified by the manufacturer and store it in a dry, protected environment when not in use.
