1. ບົດແນະນຳ
The Voltcraft Gamma-Check-A is a portable Geiger counter designed for the quick and easy detection of radioactive radiation. This instrument allows users to measure radiation dose in microsieverts per hour (µSv/h) and assess the risk of radioactive contamination in various materials, including food. Its compact design and user-friendly interface make it suitable for both personal and professional use.
Please read this manual thoroughly before operating the device to ensure safe and correct usage.

6.1 ເປີດ/ປິດ
- ເພື່ອເປີດເຄື່ອງ: ກົດຄ້າງໄວ້ OK button for approximately 2 seconds. The display will light up, and the device will begin its self-test.
- ປິດເຄື່ອງ: ກົດຄ້າງໄວ້ OK button for approximately 2 seconds until the display turns off.
6.2 ການວັດແທກ
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.
- ກົດ ເມນູ ປຸ່ມເພື່ອເຂົ້າໄປໃນເມນູການຕັ້ງຄ່າ.
