4.1 Components del dispositiu
The Mastfuyi FY8825 features a robust design with a clear color LCD display and intuitive controls.
Imatge 3: Detallada view of the detector's display and button functions.
- Botó d'encesa: Encén/apaga el dispositiu.
- CLR (Clear) Button: Clears current measurement data.
- APO (Automatic Power Off) Button: Activates/deactivates automatic power off function.
- Botó HOLD: Congela la lectura actual a la pantalla.
- Botó de silenci: Activa o desactiva les alertes sonores.
- Pantalla LCD: Shows real-time, average, and maximum radiation values, dosage unit, signal detection, and battery status.
4.2 Indicadors de visualització
The large color LCD provides comprehensive information at a glance:
- REIAL: The instantaneous radiation dose rate. This value fluctuates as radiation levels change.
- AVG: The average radiation dose rate over a period. This provides a more stable reading by smoothing out short-term fluctuations.
- MÀXIM: The highest radiation dose rate recorded since the last reset.
The unit of measurement is typically microsieverts per hour (μSv/h).
5. Configuració
5.1 Càrrega inicial
The device comes with a built-in rechargeable battery. Before first use, or if the battery indicator shows low power, charge the device using the provided USB Type-C cable and a compatible power adapter (not included).
- Connecteu el cable USB tipus C al port de càrrega del dispositiu.
- Connecteu l'altre extrem del cable a una font d'alimentació USB (per exemple, un port USB de l'ordinador, un adaptador de paret).
- The battery indicator on the LCD will show charging status. Charge until the indicator shows a full battery.
5.2 Engegada/apagada
- Per encendre: Manteniu premut el botó d'engegada (ⓘ) for approximately 2 seconds until the display illuminates.

6.2 Comprensió de lectures
The LCD displays three primary values:
- REIAL: The instantaneous radiation dose rate. This value fluctuates as radiation levels change.
- AVG: The average radiation dose rate over a period. This provides a more stable reading by smoothing out short-term fluctuations.
- MÀXIM: The highest radiation dose rate recorded since the last reset.
The unit of measurement is typically microsieverts per hour (μSv/h).
6.3 Funcions d'alarma
The device features real-time alarms to alert users to elevated radiation levels. These alarms can be configured with three modes:
- So: Una alerta sonora.
- Vibració: A tactile alert.
- Visual: A flashing color analog bar on the screen.
You can toggle the sound alert using the Mute button. The alarm thresholds can typically be set within the device's settings menu (refer to on-screen prompts or a more detailed digital manual if available for specific threshold adjustment instructions).

6.4 Advanced Detection Capabilities
The high sensitivity of the Geiger-Miller tube allows for detection in various scenarios, including:
- Industrial environments
- Medical imaging areas (e.g., X-ray/CT machines)
- Checking materials like marble, ceramic tiles, and certain food items or cosmetics for natural radioactivity.
