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. Accurate low resistances measurement 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 STANDARDS: Functionality: IEC 62271-100; IEC 62271-1; ANSI C37.09; ASTM B 539; Spain: El Real Decreto 223/2008 Electromagnetic compatibility: IEC
