The UT521 is an earth-resistance tester. It is essential for various applications to have a good earth connection, for example, to discharge over-voltage or when lightning strikes. Earth testers work with pins that must be inserted into damp soil. In addition, a connecting wire for the measuring object is included, so you can compare it with the earth.

The supplied pins are intended to measure the resistance of the earth to see if it is suitable for inserting an earth pin.

The meter can perform both 2 and 3 wire-resistance measurements, and it is also possible to measure earth-voltage.
