Micsig CP2100B AC/DC Current Probe

The Micsig CP2100B is a high-performance, compact AC/DC current probe tailored for demanding measurement tasks—ideal for motor drives, inverters, power supplies, avionics, frequency converters, and other industrial applications. It features a sleek split design, attaches via a standard BNC interface, and is conveniently powered by USB - no separate power supply needed

Core Features

  • Wide Bandwidth: Measures DC up to 2.5 MHz, enabling capture of high‑frequency current transients with precision

  • Peak & RMS Capacity: Supports measurements up to 100 Aₚₐₐ (≈70.7 A RMS), with overload detection via audible buzzer and flashing LED 

  • Dual Ranges: Switch between two current measurement ranges—10 A and 100 A—for versatile usage across light and heavy current scenarios

  • Fast Response: Achieves rise time ≤ 140 ns and signal delay under 200 ns, ensuring accurate tracking of rapid current changes

  • High Accuracy:

    • ±3% ± 50 mA at low currents (10 A range)

    • ±4% ± 50 mA at moderate currents (100 A, up to 40 Aₚₐₐ)

    • Up to ±15% at very high currents (40–100 Aₚₐₐ)

  • Safety Ratings: Rated for CAT III 300 V working voltage (floating CAT II 600 V), supporting safe operation in industrial environments 

  • Compact & Compatible: Accepts conductors up to 13 mm in diameter. Fits oscilloscopes via BNC and is adaptable to multimeters with an appropriate connector 

  • Zero Calibration: Offers both automatic and manual zero adjustments, as well as degaussing support for accurate baseline performance.
