1 General description
1.1 Features
MicroOhm 10A ( MI 3250) is a portable (2.8 kg) bidirectional low resistance ohmmeter
using four wire Kelvin method to measure low resistances of:

Switches

Relays

Connectors

Bus bars

Power distribution cable joints

Motor & generator winding

Power transformers

Power inductors

Rail track joints

Wire and cable resistance

Welding joints.
Instrument can be powered from mains or internal rechargeable batteries.
It is designed and produced with the extensive knowledge and experience acquired
through many years of of working in this field.
Available functions and features offered by the
MicroOhm 10A meter:

Resistance measurement (Four wire Kelvin method);

High Resolution measurement (24-
Bit Σ-Δ ADC)
;

Auto or Manual Range

Wide measuring range (0.1
μΩ ... 2 kΩ);

Adjustable test current (1 mA ...10 A);

Temperature compensation;

Hi/Lo limits;

Automatic thermal EMF elimination ;

Four different measuring modes (single, continuous, inductive, automatic);

USB and RS232 communication;

High overvoltage category CAT IV / 300 V .
A
320x240 dot matrix LCD 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 HVLink PRO that is supplied
as a part of standard set enables transfer of measured results to PC where can be
analysed or printed.
