6. Instruccions de funcionament

6.1. Prendre Mides

1. Assegureu-vos que el dispositiu estigui encès i completament carregat.
2. Hold the device in the area you wish to monitor. The Geiger counter will begin detecting radiation automatically.
3. Observe the display for real-time readings in µSv/h, CPM, and mR/h.
4. The device's internal motion detector will reorient the display for optimal viewing, whether held horizontally or vertically.

6.2. Comprensió de lectures

• CPM (Counts Per Minute): This indicates the number of radiation particles detected by the Geiger-Müller tube per minute. It's a direct measure of the detection rate.
• µSv/h (Microsieverts Per Hour): This is a measure of the equivalent dose rate, indicating the biological effect of radiation. It is a more standardized unit for assessing radiation exposure.
• mR/h (Milliroentgens Per Hour): Another unit for measuring exposure rate, often used in older contexts.
• Indicador d'estat: The "Normal" or "High" indicator provides a quick visual alert based on pre-set or user-defined thresholds.

6.3. Menu Navigation and Advanced Features

The GMC-500 offers various menu options for advanced functionality.
