4. Operation

4.1 Basic Measurement

1. From the main menu, navigate to Meas Setup.
2. Select the appropriate material type for your workpiece. The test results are related to the elastic constants of the workpiece.
3. Ensure the workpiece surface has a maximum roughness of Ra<15μm and a minimum thickness of 2mm. The minimum workpiece weight should be 0.3kg.
4. Place the probe firmly and perpendicularly onto the test surface.
5. Initiate the measurement as per the on-screen instructions. The device will output the Vickers hardness value within seconds.
6. Read the displayed hardness value.

4.2 Calibration

For new materials or composites, calibration is crucial to ensure accurate readings. The device supports multi-point calibration.

1. Access the Material or System menu to find calibration options.
2. Follow the on-screen prompts to perform a multi-point calibration using a known reference block for the specific material.
3. The device allows direct testing with multi-point calibration, eliminating the need for a hardness conversion table for new materials.

4.3 Data Management

The device can store up to 50 groups of measurement data. You can access stored data via the Storage menu.

• Data Export: Measurement data can be exported to an external Bluetooth printer for immediate hard copies or connected to a computer via USB for detailed analysis and record-keeping.

5. Maintenance

5.1 Cleaning

• Regularly clean the main unit and probe with a soft, dry cloth.
• Do not use abrasive cleaners or solvents, as these can damage the device's surface or internal components.
• Ensure the probe tip is free from debris before each measurement to maintain accuracy.

5.2 Battery Care

• Charge the device regularly, even if not in frequent use, to maintain battery health.
• Avoid fully discharging the battery frequently.
• Store the device in a cool, dry place when not in use.

5.3 Storage

When not in use, store the hardness tester and its accessories in the provided protective carrying case to prevent damage from dust, moisture, and impact.

6. Troubleshooting

This section addresses common issues you might encounter with your device.

6.1 Device Not Powering On

• Check Battery: Ensure the battery is sufficiently charged. Connect the charger and allow it to charge for at least 30 minutes before attempting to power on again.
• Power Button: Confirm the On/Off button is pressed and held correctly.

6.2 Inaccurate or Inconsistent Readings

• Probe Connection: Verify the probe is securely connected to the main unit.
• Probe Tip: Inspect the probe tip for wear or damage. A worn tip can affect accuracy.
• Workpiece Surface: Ensure the test surface is clean, smooth (Ra<15μm), and flat.
• Material Selection: Confirm the correct material type is selected in the device settings.
• Calibration: Perform a multi-point calibration, especially if testing a new material or if results are consistently off.
• Workpiece Size: Ensure the workpiece meets the minimum requirements (thickness > 2mm, weight > 0.3kg).

6.3 Data Export Issues

• Bluetooth Connection: Ensure Bluetooth is enabled on both the tester and the external device (printer/computer) and that they are properly paired.
• USB Connection: Verify the USB cable is correctly connected and that the computer recognizes the device.
