- За искључивање: Притисните и држите OK button for approximately 2 seconds until the display turns off.
6.2 Мерење
Once powered on, the device automatically starts measuring radiation levels. The current radiation dose rate will be displayed in µSv/h on the main screen.
- Position the device near the object or area you wish to measure.
- Allow a few seconds for the reading to stabilize. The device detects radiation in a short time.
- The display will show the real-time radiation dose.
6.3 Adjustable Alarm
The Gamma-Check-A features an adjustable alarm to alert you when radiation levels exceed a set threshold.
- Притисните тастер Мени дугме за улазак у мени подешавања.
- Користите Up (▲) и Доле (▼) buttons to navigate to the "Alarm Threshold" option.
- Притисните OK да изаберете.
