Electrical Installation Safety MULTIFUNCTIONAL INSTALLATION TESTERS MI 2088 Earth - Insulation Tester


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.


MEASURING FUNCTIONS:


• Insulation resistance with DC voltage; • Continuity of PE conductors with 200 mA test current with polarity change;


• Continuity of PE conductors with 7 mA test current (continuous measure- ment) without RCD tripping;


• Voltage; • Earth resistance (4-wire method, one clamp method, two clamps method).


• Specific earth resistance; • TRMS leakage and load currents (op- tion);


• Overvoltage protection devices test- ing.


KEY FEATURES:


• Earth resistance measurement: in- strument performs 4-wire earth re- sistance measurement with two ad- ditional rods; 4-wire earth resistance measurement in combination with an additional current clamp; earth resist- ance measurement with 2 current clamps without breaking the loop and 4-wire specific earth resistance meas- urement.


• Downloadable: downloads via RS232 cable directly to the PC with the help of the software included in the stand- ard set.


• Polarity swap: automatic polarity re- versal on continuity test.


• Insulation range: wide range of insula- tion test voltages from 50 V to 1000 V, resistance measuring range up to 30 GΩ.


• PC SW EarthLink included in the the standard set enables downloading of test results and parameters and crea- tion of test reports.


APPLICATION:


• Initial and periodic testing of domestic and industrial installations;


• Testing of single and multiphase sys- tems;


• Testing of TT and TN systems. STANDARDS:
