• Transmission Socket: Connects one lead of the probe.
• Receiving Socket: Connects the other lead of the probe.
• Backlight LED Screen: Displays measurement readings and menu options. Features adjustable contrast and LED backlight.
• Panel Kawalan: Contains buttons for menu navigation, saving data, adjusting settings, and calibration.
• Siasatan: The transducer that emits and receives ultrasonic waves.
• Measuring Block: A standard block used for calibration.

4. Persediaan

1. Sambungkan Probe: Carefully connect the probe's two leads to the Transmission Socket and Receiving Socket on the top of the device. Ensure a secure connection.
2. Hidupkan kuasa: Press and hold the power button (usually marked with MENU or a power symbol) to turn on the device. The LED screen should illuminate.
3. Gunakan Couplant: Before any measurement, apply a small amount of ultrasonic couplant to the surface of the material to be measured, or directly to the probe face. This ensures proper ultrasonic wave transmission.

5. Operating Modes and Measurement

The T8-UT200 offers three distinct measurement modes:

Figure 4: Illustration of the three measurement modes. This diagram visually explains the difference between PE mode (uncoated material), IE mode (through coating), and the general measurement process. It also notes the coating thickness requirement for IE mode.

5.1. Mod Pengukuran

• PE Mode (Pulse-Echo): Used for measuring the thickness of uncoated materials. In this mode, the ultrasonic pulse travels directly through the material and reflects from the back surface.
• IE Mode (Echo-Echo): Designed for measuring the thickness of metal through coatings (e.g., paint, rust) without removing the coating. The device measures the time difference between two consecutive echoes from the metal substrate. This mode is effective for coating thicknesses up to 1mm.
• Precious Metal Test Mode: A specialized mode for verifying the authenticity and purity of precious metals like gold and silver by measuring their thickness and comparing it against known material properties.

5.2. Calibration (V-PATH)

The T8-UT200 utilizes a V-PATH calibration model for high precision. Regular calibration ensures accurate readings.

1. Penentukuran Standard: Place the probe firmly on the integrated measuring block (or a known thickness standard) with couplant.
2. Initiate Calibration: Tekan ke CAL button on the control panel. Follow the on-screen prompts to complete the calibration process.
3. Sound Velocity Adjustment: If measuring a material with a known sound velocity different from the default, navigate to the sound velocity setting (usually via the VEL button) and adjust it accordingly. The range is 1000 ~ 9999 m/s.

5.3. Performing a Measurement

1. Pilih Mod: Use the menu buttons to select the appropriate measurement mode (PE, IE, or Precious Metal Test) for your application.
2. Gunakan Couplant: Ensure a thin layer of couplant is applied to the test surface.
3. Letakkan Probe: Press the probe firmly and perpendicularly onto the prepared surface. Maintain consistent pressure.
4. Baca Pengukuran: The thickness reading will appear on the LCD screen.
5. Penyimpanan Data: To save the measurement, press the JIMAT button. The device stores thickness values, sound velocity, and time information.

6. Penyelenggaraan

• Pembersihan: After each use, wipe the probe and the device's surface with a soft, dry cloth to remove any couplant residue or dirt. Do not use abrasive cleaners or solvents.
• Penjagaan Probe: Handle the probe carefully. Avoid dropping it or subjecting it to harsh impacts. Ensure the probe face is clean and free from scratches.
• Storan: Store the device and its accessories in the provided packing box in a cool, dry place, away from direct sunlight and extreme temperatures.
• Penggantian Bateri: If the device uses replaceable batteries, replace them when the low battery indicator appears on the screen to ensure optimal performance.
