Standard multimeters may give inaccurate readings on such waveforms, while the YS-4470 delivers precise results every time, making it essential for modern power electronics diagnostics.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the YS-4470 Multimeter require an external shunt for current measurement?\u003c\/h4\u003e\n\u003cp\u003eA: No. The YS-4470 features a built-in ammeter function that allows direct current measurement up to 10A (fuse-protected), eliminating the need for an external shunt and simplifying high-load testing setups.\u003c\/p\u003e\n\u003ch4\u003eQ: Is a battery included with the YS-4470 Multimeter Kit?\u003c\/h4\u003e\n\u003cp\u003eA: No, a battery is not included with the kit. Please ensure you have a compatible battery on hand before use.
