1. Product Overview
The OSS W01 Inductance Tester is a high-precision, stable, and easy-to-operate tool designed for quickly checking the functionality of inductances on phone motherboards. It utilizes electromagnetic induction to detect faults, making troubleshooting efficient for repair technicians.


2. Setup
- Power Supply: The OSS W01 Inductance Tester is powered via a Type-C interface. Connect a standard Type-C charger lead to the power interface on the device. No internal battery is required.
- Preparation: Ensure the motherboard or component to be tested is clean and free from debris.


3. Operating Instructions
Follow these steps to use the OSS W01 Inductance Tester:
- Plug in the Type-C charger lead to power on the device.
- Press and hold the detection button.
- Bring the sensing end (the pointed tip) of the tester close to the inductance you wish to detect on the motherboard.
- Observe the detection indicator light:
- If the green light is ON, it indicates that the inductance is working normally and has no damage.
- If the green light is NOT ON, it indicates that the inductance is working abnormally or is damaged.


4. Maintenance
- Keep the device clean and dry. Wipe with a soft, dry cloth.
- Avoid exposing the device to extreme temperatures, humidity, or corrosive substances.
- Store in a safe place to prevent physical damage to the sensing end or Type-C port.
5. Troubleshooting
The primary troubleshooting method for the OSS W01 involves observing the indicator light:
- Indicator Light Not On (when expected to be):
- Ensure the Type-C power cable is securely connected and providing power.
- Verify that the detection button is being pressed firmly.
- If the light remains off when testing a known good inductance, the device may require service. - Inconsistent Readings:
- Ensure the sensing end is making proper contact or is sufficiently close to the inductance.
- Check for any physical damage to the sensing end.
- Clean the motherboard area around the inductance to ensure no interference.
