- Taal: Kies jou voorkeurtaal.
- Eenhede: Switch between measurement units such as uSv (microsieverts) and uGy (micrograys).
- Horlosie: Set the current year, month, and day.
5. Bedryfsinstruksies
5.1 Radiation Measurement
From the main interface, the device displays real-time dose rate, average dose rate, and total accumulated dose. The sensor is located on the right side; ensure this side is positioned towards the area or object you wish to monitor for optimal accuracy.
5.2 Tydmetermeting
The timer measurement function allows for scheduled monitoring. In the timer measurement menu, you can set:
- Begin vertraging: Set a delay from 00-99 hours before measurement begins.
- Meting Tyd: Define the duration of the measurement from 00-999 hours.
Each completed timer measurement automatically saves a history record. The device can store up to 10 history records.
5.3 Alarminstellings
The HFS-20 features sound and light dual alarms. You can customize the alarm settings:
- Over-Limit Alarm: Set the instantaneous dose alarm limit (range: 0.1 uSv - 999 uSv).
- Total Dose Alarm: Set the accumulated dose alarm limit (range: 1 uSv - 9999 uSv).
- Alarmvolume: Adjust the volume of the audible alarm.
- Aantal alarms: Configure how many times the alarm sounds.
