1 General description
1.1 Features
EI (Earth – Insulation) Tester (MI 3288) is a Multi-function, portable battery (Li-ion) test
instrument with excellent IP protection IP54, intended for: Voltage and frequency measurement
(TRMS), Insulation resistance measurement up to 2,5 kV, Earth resistance and impedance,
Specific earth resistance, Earth potential and continuity (7 mA, 200 mA) measurement. It is
designed and produced with the extensive knowledge and experience acquired through many
years of working in this field.
Available functions and features offered by the MI 3288 Tester:
➢ Voltage and frequency measurement up to 1 kV TRMS;
➢ Earth Impedance or Resistance 2, 3, 4 – pole;
➢ Selective Earth Impedance (Iron Clamp);
➢ 2 Clamps measurement;
➢ Specific Earth Resistance ρ (Wenner, Schlumberger method);
➢ Earth Potential;
➢ Insulation measurement from 50 to 2500 V;
➢ Polarization Index (PI) and Dielectric Absorption ratio (DAR);
➢ Dielectric Discharge ratio (DD);
➢ Capacitance measurement;
➢ Varistor test (Over-voltage Protection Devices);
➢ Ω - Meter (7 mA and 200 mA);
➢ Current RMS Measurement;
➢ Auto Sequence®;
➢ Visual Test;
➢ Memory Organizer.
A 4.3'' (10.9 cm) colour LCD display with touch screen offers easy-to-read results and all
associated parameters. The operation is straightforward and clear to enable the user to operate
the instrument without the need for special training (except reading and understanding this
Instruction Manual).
Test results can be stored on the instrument. PC software that is supplied as a part of standard
set enables transfer of measured results to PC where can be analysed or printed.
