Description
The grounding tester allows you to measure the grounding system without disconnecting the ground line of the circuit or the need for auxiliary electrodes. It can measure resistance from 0.01Ω with a resolution of 0.001Ω and leakage current up to 30A. The double insulation of the terminals makes them durable tools for outdoor work and effectively blocks out disturbing signals from the environment. The meter is equipped with an RS-232 interface that allows the device to be connected to a computer and operated by means of dedicated software.
