Frequently Asked Questions

Q: What types of inductors can the CT-1 coil tester check?

A: The CT-1 inductance tester is compatible with a wide variety of inductor and coil types commonly found on motherboards, PCBs, power supplies, and general consumer electronic devices. It is suitable for both SMD (surface-mount) and through-hole inductor styles.

Q: How does the CT-1 inductor tester indicate a faulty coil?

A: The CT-1 uses a simple green LED indicator. When you place the inductor on the tester and press the button, a green light ON signals the inductor is functioning correctly. If the light does NOT illuminate, the coil or inductor is likely faulty and should be replaced.

Q: Do I need any special skills or equipment to use the CT-1 coil tester?

A: No special technical skills are required. The one-button operation makes it accessible to both beginners and experienced technicians. No additional equipment is needed — just place, press, and read the result.

Q: Is the CT-1 inductance tester portable enough for field repairs?

A: Absolutely. At just 7 × 3.5 cm, the CT-1 is compact and lightweight, making it easy to carry in a tool bag or pocket for on-site motherboard and PCB diagnostics wherever you need it.
