Inductor Handheld EMF Pulse Inductor Tester for Laptop Motherboard Repair
This compact diagnostic tool is designed to detect high-frequency electromagnetic pulses emitted by PWM coils on laptop motherboards. It allows technicians to quickly identify switching activity in critical power rails—such as CPU, GPU,POWER SYSTEM or charging circuits, without the need for pulse trigger test with oscilloscope.
Simply place the tester near a motherboard inductor; if switching pulses are present, the onboard Green LED will turn on. This makes it an essential tool for diagnosing issues like dead CPU rails, shorted VRMs, or missing gate drive signals during board-level repair.
Detect Missing Switching on Key Power Rails
Identify inactive S5, S0, VCORE, or VCCGT rails with ease.
Pinpoint Faulty Components
Helps locate issues such as open coils, circuit bad MOSFET drivers, or failing PWM controllers.
High-Frequency EMF Detection
Sensitive to switching frequencies from 100 kHz up to several MHz.
Instant Visual Feedback
LED indicator on when switching pulses are detected.
Specs:
Power: CR2032 coin cell ( not included )
Indicator: Red LED for for POWER & Green LED for pulse detection
Trigger range: 100 kHz – 5 MHz
Size: Compact and fits any technician’s toolkit
