4. 操作手順

4.1 Basic Hardness Measurement

The Mxmoonfree hardness tester utilizes the Leeb rebound principle for non-destructive testing. A small impact body is propelled onto the test surface, and the rebound velocity is measured to determine hardness.

測定を実行するには:

1. Sを準備するamp上： Ensure the test surface is clean, smooth, and free from scale, oil, or other contaminants. The sample should be stable and have sufficient mass to prevent movement during impact. For small objects, use the included support ring to stabilize the tester.
2. Select Material and Scale: 使用 マット button to select the material type (e.g., Steel and Cast Steel). Use the 規模 button to choose the desired hardness scale (e.g., HL, HB, HRC, HV, HS, HRB, HRA).
3. センサーの位置: Place the sensor firmly and perpendicularly on the test surface.
4. 測定開始: Press the button on the sensor to release the impact body. The hardness value will be displayed on the screen. Repeat measurements as needed for accuracy.

4.2 Multi-Hardness Unit Conversion

The device supports instant conversion between up to 7 different hardness scales. After a measurement, press the 規模 button to cycle through the available units (HL, HB, HRC, HV, HS, HRB, HRA).

6. メンテナンス

適切なメンテナンスを行うことで、デバイスの寿命と精度が確保されます。

• クリーニング： Regularly wipe the device and sensor with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• ストレージ： Store the hardness tester and its accessories in the provided rugged carrying case when not in use. Keep it in a dry environment, away from extreme temperatures and direct sunlight.
• Impact Device Care: Ensure the impact device is clean and free of debris. Do not lubricate the impact device unless specifically instructed by Mxmoonfree support.

7。 トラブルシューティング

If you encounter issues with your Mxmoonfree Digital Leeb Metal Hardness Tester, consider the following:

• 不正確な読み取り: If you suspect inaccurate readings, perform a calibration using the standard hardness block as described in Section 5. Ensure the test surface is properly prepared and the sensor is positioned correctly.
• デバイスの電源が入っていない: Check the battery level. If the device uses replaceable batteries, ensure they are inserted correctly and are not depleted.
• Connectivity Issues (PC Software): Ensure the USB cable is securely connected to both the tester and the PC. Verify that the PC software is installed correctly. If you experience issues with USB connectivity, contact customer support, as some units may have had manufacturing variations.
• センサーの誤動作： If the sensor does not impact or rebound correctly, ensure it is clean and properly connected. Avoid dropping or subjecting the sensor to harsh impacts.

For persistent issues or technical support, please refer to Section 9: Warranty and Support.
