6. Operating Instructions
6.1 Powering On/Off
- To Power On: Press and hold the orange Power Button until the LCD screen illuminates.
- To Power Off: Press and hold the orange Power Button until the device shuts down.
6.2 Understanding the Display
The LCD display shows key radiation information:
- Dose Rate: Displayed in μSv/h (microsieverts per hour), updated per second. This indicates the current level of radiation.
- Cumulative Dose Equivalent: Shows the total accumulated radiation dose over time.
6.3 Setting Alarms
The device supports various alarm settings:
- Press the MENU/OK button to enter the settings menu.
- Use the Up and Down arrow buttons to navigate to the alarm settings.
- Press MENU/OK to select and adjust alarm thresholds for dose rate and cumulative dose. The device offers 3 alarm modes and various thresholds.
- Confirm your settings by pressing MENU/OK.
- A protection alarm will sound if the dose rate exceeds the set threshold, typically within 5 seconds.
6.4 Real-time Monitoring
The FS2011 provides 24-hour real-time monitoring. Once powered on, it continuously measures and displays radiation levels. Users can monitor the environment for beta, gamma, and X-ray radiation.
