Open jaw design - Digital current meter with a fixed jaw for automatic, non-contact measurement of AC and DC current from 1 to 100 A. Manual mode is also available. TRMS multimeter - Smart multimeter standard with easy operation. Automatically measures AC and DC voltage, resistance, and continuity with high resolution. All functions are also available in manual mode. 3 in 1 multifunction - This device functions as a multimeter, ammeter, and a contactless voltage tester. It also measures capacitance, diode, frequency, and duty cycle, and can search for live wires. Small and portable - Compact and refined design, pocket-sized for easy carrying. Especially suitable for testing in tight spaces such as hubs or dense wiring. Curved buttons and ergonomic housing provide a comfortable grip. Usage scenarios - In electrical installations or maintenance, quickly verify currents up to 100 A without disconnecting circuits using the non-contact measurement while still having manual mode for direct contact readings when needed. - Home electrical troubleshooting: test AC/DC voltage, resistance, continuity, plus diode and capacitor-related checks to diagnose wiring, outlets, and devices with a single tool. - Field servicing in crowded or confined environments such as server rooms, telecom cabinets, or dense wiring hubs where a compact, pocket-friendly tool enables measurements without removing other components.
