Measurement Method

Measurement of the earth electrode resistance (3-Pole method)

The international standard IEC 60364-6 provides information regarding the measurement of the resistance of an earth electrode for TT, TN and IT systems.
This measurement shall be made by the Volt-Amperometric method using two auxiliary earth electrodes.
The instrument that covers this requirement is the Earth Tester.

Measurement of the simplified earth resistance (2-Pole method)

Various features

Dust and Waterproof

After use you can wash it to remove the mud and dust.

Strong noise rejection

Noise rejection up to 25V rms allows accurate testing in noisy environments.

Earth voltage warning

A red LED comes on if an external voltage is detected.

【LED light comes on if:】

0 - 10Hz > 10V
10 - 100Hz >25V
100 - 400Hz >5V

Robust steel made earth spikes

Earth measurements are possible up to 100kΩ* of auxiliary earth spikes resistance.
*20Ω range 10kΩ, 200Ω range 50kΩ, 2000Ω range 100kΩ.

Auxiliary earth resistance check

4105DLBT-H checks if the auxiliary earth resistance is:
