Suitable for
Testing grounding systems in power distribution networks
Verifying electrical installations in residential and commercial buildings
Inspecting lightning protection systems
Conducting routine maintenance on electrical grounding grids
This meter may not be suitable for high-voltage transmission line testing where specialized high-current injection equipment is required. It is also not designed for measuring insulation resistance or continuity in non-grounding related electrical circuits.
Key specifications
Measurement range: 0.01 to 2000 Ohm
Earth voltage measurement capability
Data storage: Up to 20 sets
Data hold function
Digital display with backlight
To use the UNI-T UT522, connect the test leads to the grounding electrode and the auxiliary earth spikes according to the standard three-pole measurement method. Ensure the area is clear of debris and that the spikes are driven firmly into the soil to achieve a low-resistance contact. Select the appropriate resistance range on the device, initiate the measurement, and record the value once the reading stabilizes on the screen. Use the data storage function to save results for later review.
What to consider before purchase
Ensure you have the necessary auxiliary earth spikes and test leads for your specific site requirements
Verify that the measurement range covers the expected resistance values of your grounding system
Consider the soil conditions at your testing site, as dry or rocky soil may require additional preparation for accurate readings
Usage recommendations: Always perform a visual inspection of the grounding system before testing. Ensure that all connections are clean and secure to prevent measurement errors. Regularly calibrate the device to maintain accuracy over time.
