Metrel MI 3250 MicroOhm 10A Low Resistance Ohmmeter
Measuring Functions
Bidirectional resistance measurement from 0.1 μΩ up to 2000 Ω with test current up to 10 A.
Temperature compensation (available with optional temperature probe).
Key Features
High Efficiency: Generates 10 A into a 200 mΩ load for 15 minutes without overheating.
Robust Protection: High overvoltage protection (CAT IV / 300 V) and internal protection circuits against inadvertent connection to live lines.
PASS/FAIL Evaluation: Custom limits can be set for instant evaluation; includes 50 Hz / 60 Hz ripple detection and rejection.
Dual Powering: Can be powered by mains or internal rechargeable batteries; instrument remains usable while the fast charger is active.
User Interface: Large 320 x 240 dot matrix LCD provides easy-to-read results and associated parameters.
Data Management: Internal memory stores up to 1,000 test results with timestamps; PC SW HVLink PRO included for analysis and reporting.
Portable: Lightweight design optimized for field use in substations and industrial environments.
