4. Betjeningsvejledning
4.1 Basic Operation and Measurement
Once powered on, the device will immediately begin detecting radiation and displaying real-time data on the LCD screen. The main display shows:
- Real-time detection quantity (current dose rate)
- Maximum detected value
- Average detected value
- Temperatur og luftfugtighed
- Current alarm value
- Akkumuleret tid

4.2 Setting Alarm Modes
The detector offers three distinct alarm modes to alert you when radiation levels exceed a preset threshold:
- Hørbar alarm: A beeping sound.
- Vibrationsalarm: Enheden vibrerer.
- Flashing Light Alarm: LED lights on the device flash.
You can preset the cumulative dose alarm threshold. When the detected cumulative dose exceeds this value, the selected alarm mode(s) will activate.
- Tryk på Right / Settings knappen for at åbne indstillingsmenuen.
- Naviger ved hjælp af Up og Ned buttons to find "Alarm Settings" or "Ala Mode".
- Trykke OK at vælge.
- Adjust the alarm threshold and select your preferred alarm mode(s) (light, vibration, sound) using the navigation buttons and OK for at bekræfte.
- Tryk på Left / Back button to exit the settings.
