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.
Measuring Functions:
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.
Key Features:
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.
Application: 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
