Product Overview

Micsig CP Series features 1% accuracy and 1 mA resolution for precise waveform capture and reliable measurements.A dual-range design covers both small-signal detection and high-current transient analysis, helping engineers optimize their designs. Featuring 5 mm jaw, one-button degauss/auto-zero, and a built-in overcurrent alarm, the CP Series ensures easy operation and safety. The standard BNC interface is compatible with most oscilloscope brands, making it ideal for new energy and industrial electronics testing.
* Product appearance may vary by version without affecting performance or functionality.

Excellent Design

Auto Degaussing and Zero: effortless, efficient, and precise.

Overcurrent alarm for safe range switching and reliable protection.

Standard BNC interface compatible with most oscilloscope brands.

HF Current Signal Measurements

Accurate measurement capability on high-frequency signals >20MHz. (CH1 Yellow, measured with the CP1003B).

Same signal completely distorted when measured by low-frequency probe. (CH2 Blue).

Observe Surge Current

Accurately capture the surge current waveform when the power adapter starts (Measured with the CP503B).
