2. Product Advantages

2.1 Compact and Exquisite Design, Revolutionizing Spatial Measurement Experience

Featuring a 190g lightweight body and a compact 7×4×1.7cm control module (merely 1/3 the size of conventional current probes), its miniaturized design (with 5mm jaw diameter) enables one-handed operation. The ultra-slim profile allows effortless access to confined spaces like densely-packed PCB traces or equipment interiors, eliminating environmental constraints for high-frequency current measurements.

2.2 Ultra-Wide Bandwidth and High-Frequency Response
CP1003B: Bandwidth up to DC-100MHz, rise time ≤3.5ns, precisely reconstructing signals above 20MHz.

CP503B: Bandwidth DC-50MHz, rise time ≤7ns, suitable for medium/high frequency switching power supply (below 50kHz) measurement.

2.3 Dual-Range Precision Measurement Architecture
5A Range (1X): 1mA resolution supports 5A continuous current (RMS), ideal for monitoring chip leakage current and sensor weak signals.

30A Range (10X): Supports 30Arms continuous current (RMS), enabling observation of surge currents and adapting to high-current testing of power modules.

2.4 Intelligent Operation and Safety Protection

One-Touch Demagnetization/Auto-Zero: Press the "Zero" button to simultaneously execute demagnetization and zero calibration.

Overload Indication: When the current is overloaded, the corresponding range indicator light flashes to remind range switching and ensure testing safety.

Standard BNC Interface: Compatible with all oscilloscope brands for plug-and-play operation.
