3.2 Battery Installation

1. Locate the battery compartment on the rear of the device.
2. Open the battery cover.
3. Insert three (3) 1.5V AAA batteries, ensuring correct polarity.
4. Close the battery cover securely.

Note: Batteries are not included due to air transport regulations.

3.3 Transducer Connection

1. Connect the transducer cable to the receive sockets on the top of the main unit.
2. Ensure the connections are firm to prevent signal loss.

4.2 Basic Thickness Measurement

1. Ensure the transducer is properly connected and the device is powered on.
2. Apply a small amount of coupling gel to the surface of the material to be measured. This is crucial for sound transmission.
3. Place the transducer firmly and flat against the prepared surface.
4. The thickness reading will appear on the LCD. Observe the coupling status indicator to ensure a good connection.
5. Remove the transducer and clean any remaining coupling gel.

4.3 Unit Selection (mm/inch)

Press the INCH button to toggle between millimeters (mm) and inches (inch) measurement units.

5. Calibration

The AS860 features auto-calibration to ensure measurement accuracy. For optimal results, perform calibration on a known thickness sample of the material being tested, or use the built-in calibration block if provided.

1. Press the CAL button (often labeled 'ENTER/CAL').
2. Follow the on-screen prompts to complete the calibration process. This typically involves measuring a known thickness.

6. Sound Velocity Measurement

This function allows you to determine the sound velocity of an unknown material if its thickness is known, or to select from 12 pre-set sound velocities for common materials.

1. Press the VEL DEL button to enter sound velocity mode.
2. To measure sound velocity: Input the known thickness of the material. Place the transducer on the material. The device will calculate and display the sound velocity.
3. To select pre-set sound velocity: Use the arrow buttons to scroll through the 12 available material sound velocities. Confirm your selection.

7. Data Storage

The AS860 includes a data storage function. Refer to the on-screen menu or specific buttons (if available) to save and recall measurement data. Consult the device's display for instructions on navigating the data storage menu.

8. Maintenance

8.1 Cleaning

After each use, wipe the transducer and the main unit with a soft, dry cloth. Remove any residual coupling gel from the transducer face. Do not use abrasive cleaners or solvents.

8.2 Storage

Store the AS860 in a dry environment with relative humidity below 90%. Avoid storing the device in areas with violent vibration, erosive materials, or extreme temperatures. The recommended operation temperature is 0°C to 40°C. The temperature of the workpiece should be below 60°C.

9. Troubleshooting

• No Reading / Unstable Reading:
  • Ensure sufficient coupling gel is applied.
  • Press the transducer firmly and flat against the surface.
  • Check for proper transducer connection.
  • Verify the material's sound velocity setting is correct.
• Low Battery Indication:
  • Replace the three (3) 1.5V AAA batteries immediately to ensure accurate operation.
• Device Does Not Power On:
  • Check battery installation and ensure batteries are fresh.

10. Specifications

11. Safety Information

• Do not expose the device to violent vibration, corrosive materials, or extreme temperatures.
• Avoid impact and humidity.
• Do not attempt to disassemble or modify the device, as this will void the warranty and may cause damage or injury.
• Keep the device out of reach of children.
• Dispose of batteries according to local regulations.
