2. Calibration

For accurate measurements, perform auto calibration:

1. Apply a small amount of coupling agent to the surface of the calibration block (or a known thickness sample).
2. Press the CAL button.
3. Place the transducer firmly onto the prepared surface. The device will automatically calibrate.
4. Wait for the "Coupling status indicator" to confirm successful coupling.

3. Taking a Measurement

1. Ensure the surface of the material to be measured is clean and free of debris.
2. Apply a small amount of coupling agent to the measurement point on the material.
3. Place the transducer firmly and flatly onto the prepared surface.
4. The thickness reading will be displayed on the LCD screen.
5. Observe the "Coupling status indicator" to ensure good contact. If the indicator is unstable, adjust the transducer position or reapply coupling agent.

4. Adjusting Sound Velocity / Thickness Unit

Use the VEL button to adjust sound velocity or the ▲ and ▼ keys to change the thickness unit or value.

5. Storing and Recalling Data

The device can store up to 10 thickness measurements:

• To store a measurement, press the STORE button after a stable reading is obtained.
• To recall stored data, press the STORE button repeatedly to cycle through the stored measurements.

Maintenance

• Cleaning: After each use, wipe the transducer and the main unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device and its accessories in the provided carrying case () in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display to ensure optimal performance. Remove batteries if the device will not be used for an extended period.
• Transducer Care: Handle the transducer with care. Avoid dropping it or exposing it to harsh impacts.
