4. Impostazione

4.1 Installazione della batteria

The UT343D requires two AA batteries for operation.

1. Locate the battery compartment on the back of the device (Component 11 in Figure 3).
2. Aprire il coperchio del vano batterie.
3. Inserire due batterie AA, assicurandosi della corretta polarità (+/-).
4. Chiudere saldamente il coperchio del vano batterie.

4.2 Accensione/Spegnimento

• Per accendere il dispositivo, premere il pulsante Pulsante di accensione (Component 3).
• Per spegnere il dispositivo, tenere premuto il pulsante Pulsante di accensione until the screen turns off. The device also features a 5-minute automatic shutdown function to conserve battery life.

5. Funzionamento

5.1 Misurazione di base

The UT343D automatically identifies the substrate type (Fe or NFe) and displays the coating thickness.

1. Assicurati che il dispositivo sia acceso.
2. Posizionare il Assemblaggio del sensore (Component 8) firmly and perpendicularly onto the coated surface.
3. The measurement will be displayed on the Schermo LCD (Component 2). The device will also indicate the substrate type (Fe for magnetic, NFe for non-magnetic).
4. For continuous measurement, slide the probe across the surface. For single-point measurement, lift and re-place the probe for each reading.

5.2 Calibrazione

Regular calibration ensures the accuracy of your measurements. The device supports single-point and two-point calibration.

5.2.1 Calibrazione zero

1. Posizionare il Assemblaggio del sensore directly onto the bare (uncoated) substrate of the material you intend to measure.
2. Premere il tasto Pulsante ZERO (Component 5). The display should show "0.0" or a value very close to zero.
3. This sets the baseline for subsequent measurements on that specific substrate.

5.2.2 Calibrazione a due punti

For enhanced accuracy, especially when measuring specific coating thicknesses, use two-point calibration with known thickness foils.

1. Perform Zero Calibration as described above.
2. Place a calibration foil of known thickness (e.g., 100µm) onto the bare substrate.
3. Posizionare il Assemblaggio del sensore onto the calibration foil.
4. Enter the calibration menu (refer to the full manual for detailed menu navigation using OK/MENU and arrow buttons). Adjust the displayed value to match the known thickness of the foil.
5. Repeat with a second calibration foil of a different known thickness (e.g., 500µm) if desired, following similar steps.
6. Salvare le impostazioni di calibrazione.

5.3 Limit Settings and Warning Lights

The UT343D allows users to set upper and lower measurement limits (0-1200µm). The tri-color LED warning lights provide immediate visual feedback:

• Luce rossa: Indicates the measured thickness is below the set lower limit.
• Luce gialla: Indicates the measured thickness is above the set upper limit.
• Luce verde: Indicates the measured thickness is within the acceptable limits.

6. Gestione dei dati

6.1 Conservazione dei dati

The UT343D can store up to 500 groups of measurement data. This data includes individual readings, average, minimum, and maximum values.

• To access stored data, navigate through the device's menu using the OK/MENU and arrow buttons.
• Specific instructions for saving and recalling data groups are detailed in the comprehensive user manual.

6.2 Trasferimento dati USB

Transfer measurement data to a computer for further analysis and reporting.

1. Connect the UT343D to your computer using the provided USB cable. The USB communication interface is Component 10.
2. Install the necessary software/drivers (if required, typically provided on a CD or available for download from the manufacturer's webposto).
3. Follow the software instructions to download and manage your stored data.

7. Manutenzione

• Pulizia: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the sensor assembly is kept clean and free of debris.
• Magazzinaggio: Store the device in a dry, cool environment, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Sostituzione della batteria: Sostituire le batterie quando sullo schermo compare l'indicatore di batteria scarica.
• Calibrazione: Perform regular calibration as needed, especially before critical measurements or if accuracy is suspected to have drifted.
