When you hold the probe near a coil on a powered board, the green LED lights up if the inductor is normal. If the LED turns off, it signals an anomaly in that coil — helping you pinpoint the fault location quickly and accurately.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the mainboard need to be powered on during testing?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Both the DT-001 tester and the motherboard under test must be powered on simultaneously for the electromagnetic induction detection to work correctly. Testing on an unpowered board will not yield valid results.\u003c\/p\u003e\n\u003ch4\u003eQ: What battery does the DT-001 use, and is it included?\u003c\/h4\u003e\n\u003cp\u003eA: The DT-001 is powered by a standard CR2032 coin cell battery, which is included in the package. No additional purchases are needed — simply remove the battery tab and start testing right away.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this tool suitable for both mobile phone and computer motherboard repairs?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The DT-001 is designed for use on both mobile phone mainboards and computer motherboards. Its compact 71 × 30 mm form factor makes it easy to maneuver around the tight components found on both types of boards.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
