The MI 2088 Earth – Insulation Tester is a high professional, multifunctional, portable test instrument intended for carrying out earth resistance, insulation resistance and continuity of protection conductors measurements. The Earth – Insulation Tester enables 4-wire earth resistance measuring method, 4-wire earth resistance method in combination with one clamp, two clamps earth resistance measurement, 4-wire specific earth resistance measurement and TRMS current measurement. Besides the breakdown voltage of overvoltage protection devices can be checked by the instrument. All the results can be saved on the instrument and then downloaded with the help of the EarthLink software to the computer for evaluation and report generation after testing. The MI 2088 Earth – Insulation Tester performs earth resistance, continuity, insulation and voltage measurements required by the EN 61557 standard.
