Key Features:

The MI 3252 MicroOhm 100A is a portable low resistance ohmmeter used to measure low contact resistances of breakers and switches, busbars using test current from 100 mA to 100 A.

• Safe: sustain external voltages in case of wrong connection, protection level (CAT IV, 50 V); automatically detects continuity in current circuit.

• Single and continuous measuring mode.

• Portable: rugged carrying case with a handle and lightweight design enable easy moving the instrument between sites.

• High protection degree: IP 64.

• Custom limits: the limits can be set for PASS or FAIL evaluation of test result.

• Battery powered: the instrument enables measurements with 100 A for up to 10 minutes when powered from internal battery only.

• Memory: built-in memory enables storage of up to 1000 test results.

• Downloadable: downloads test results via RS232 or USB cable directly to the PC with the help of the software.


• Resistance measurement: wide measuring range (10

  μΩ ... 20 Ω) with high accuracy 0.25 % of reading and

  resolution down to 1 nΩ, adjustable test current (100 mA

  ... 100 A);
• Voltage drop measurement;
• Bar graph: on screen resistance bar graph.


Measurement of the resistance of:
• High, middle and low voltage circuit breakers
• High, middle and low voltage disconnecting switches
• High current bus bar joints
• Cable splices
• Welding joints
