Profile:

A human-centric designed tester with high-frequency switching power supply and digital circuit tech. It outputs DC 50A/100A, offers 0.01μΩ stable resolution, and features data storage, printing, U-disk transfer, outperforming imported micro-ohmmeters.

Features:

  1. Large continuous current output (50A/100A) effectively breaks through contact oxide films, avoiding drawbacks of pulsed power.
  2. High stability: Last digit of display stabilizes within ±1 word under severe interference, ensuring repeatable readings.
  3. Ultra-high precision: Dual 16-bit Σ-Δ AD sampling and digital signal processing, achieving 0.01μΩ stable resolution.
  4. Intelligent: Imported high-performance CPU with auto-range switching and over-temperature protection for safe operation.
  5. Premium quality: Imported key components, temperature compensation circuit, and military-grade connectors for vibration resistance.
  6. Flexible settings: Selectable current gears and customizable test time (5s~599s) exceeding standard 60s requirement.
  7. User-friendly: Rotary mouse input, date/time setting, real-time data storage, and instant printing.
  8. U-disk transfer: Export data via USB for further analysis with upper computer software.
  9. Portable: Compact size and lightweight design for easy on-site carrying and use.
