1. Introduction
The OSS TEAM W01 Type-C Inductance Tester is a specialized tool designed for quick and accurate detection of inductance faults in mobile phone motherboards and other electronic components. Utilizing electromagnetic induction, this compact and stable device helps identify faulty inductors by indicating their operational status via an LED light.

2. Product Components
Figure 2: W01 Inductance Tester Component Overview
- Power Interface: Type-C port for 5V power supply.
- Detection Button: Activates the inductance detection function.
- Detection Indicator Light: Green LED that indicates the status of the inductor.
- Detection Terminal: The probe tip used to approach the inductor.
3. Setup
- Power Supply: Connect a 5V Type-C power source (e.g., a phone charger or power bank) to the Type-C Power Interface on the W01 tester. The tester itself does not have an internal battery.
- Prepare Device Under Test: Ensure the motherboard or circuit board containing the inductors you wish to test is powered on. The W01 tester requires the target inductor to be part of an active circuit to function correctly.
4. Operating Instructions
The W01 Inductance Tester operates on the principle of electromagnetic induction to detect the integrity of coil-type inductors.
- Activate Tester: Press and hold the Detection Button on the W01 tester.
- Position Probe: Carefully bring the Detection Terminal (probe tip) of the W01 tester close to the inductor you want to test. The optimal distance is 1-3 millimeters from the inductor. Do not press tightly or make direct contact if the inductor is not insulated.
- Observe Indicator Light:
- Green Light On (Solid or Flashing): This indicates that the inductor is working normally, and its coil is intact.
- No Light: If the green light does not illuminate, it signifies that the inductor is faulty (e.g., an open circuit in the coil) and requires repair or replacement.
- Test Multiple Inductors: Repeat steps 1-3 for each inductor you need to test.

5. Maintenance
- Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Store the tester in a dry environment, away from extreme temperatures and direct sunlight.
- Avoid dropping the device or subjecting it to strong impacts.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tester LED does not light up for a known good inductor. |
|
|
| LED lights up when near metal parts (heatsinks, shields). | Electromagnetic interference. | This is normal interference and not a valid reading for inductance. Focus testing only on coil-type inductors. |
| Inconsistent readings (light blinks or doesn't blink on same component). |

8. User Tips
- Power is Key: Always ensure both the W01 tester and the circuit board you are testing are properly powered on for accurate results.
- Maintain Distance: Keep the probe tip 1-3mm away from the inductor. Too close or too far can lead to inaccurate readings.
- Focus on Inductors: This tool is specifically for coil-type inductors. It will not accurately test resistors, capacitors, diodes, or transistors.
- Beware of Interference: If the LED lights up near metal heatsinks or shields, this is interference, not an indication of an inductor's status.
