1. Introduction
The MaAnt M093 and M093B are innovative and practical inductance testers designed for quick fault detection on electronic motherboards using electromagnetic induction. These tools provide a simple and efficient way to check the working condition of inductors, making them essential for PC repair and electronics troubleshooting.


2. Models
- MaAnt M093: This model is powered by button batteries (not included).
- MaAnt M093B: This model features a USB Type-C port for power supply.
3. Setup
3.1. MaAnt M093 (Button Battery Model)
- Locate the battery compartment on the device.
- Insert the required button batteries (not included) into the compartment, ensuring correct polarity.
- Close the battery compartment securely.

3.2. MaAnt M093B (USB Type-C Model)
- Connect a standard USB Type-C cable to the device's Type-C port.
- Connect the other end of the USB cable to a compatible power source (e.g., USB charger, computer USB port).
- The device will power on automatically.
4. Operating Instructions
The MaAnt Inductance Tester utilizes electromagnetic induction for quick and accurate fault detection. Follow these steps to operate the device:
- Power On: Ensure the device is powered on (either by inserted batteries for M093 or USB-C connection for M093B).
- Position Probes: Gently place the two probes at the tip of the tester onto the inductor you wish to test on the electronic motherboard.
- Observe Indicator Light:
- If the green light is on during the detection, it indicates that the inductance is normal and the inductor is working properly.
- If the detection light is not on, it indicates abnormal operation or damage to the inductor.
- Repeat: Move to other inductors as needed to identify all faulty components.


5. Maintenance
- Cleaning: Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the inductance tester in a dry, cool place away from direct sunlight and extreme temperatures.
- Battery Replacement (M093): If the device does not power on or the indicator light is dim, replace the button batteries with new ones of the correct type and voltage.
- Probe Care: Ensure the probes are clean and free from corrosion or damage for accurate readings.
6. Troubleshooting
- Problem: Device does not power on / Indicator light does not illuminate.
- Solution for M093: Check if the button batteries are inserted correctly and have sufficient charge. Replace batteries if necessary.
- Solution for M093B: Ensure the USB Type-C cable is securely connected to both the device and a working power source.
- Problem: Green light does not turn on when testing a known good inductor.
- Solution: Ensure the probes are making good contact with the inductor. The device might be faulty; contact support if the issue persists.
- Problem: Inconsistent readings.
- Solution: Clean the probes and ensure they are not damaged. Ensure stable contact with the inductor. Test on a known good inductor to verify device functionality.
