5.1 Eadar-aghaidh sgrùdaidh
The main screen displays real-time radiation data, including:
- Current Dose Rate: Instantaneous radiation level (e.g., μSv/h).
- Average Dose Rate: Average radiation level over a period.
- Maximum Dose Rate: Highest radiation level detected.
- Cumulative Dose: Total accumulated radiation dose since the last reset.
- Waveform Monitoring: A graphical representation of radiation levels over time can be accessed from the main interface.

6. Cumail suas
6.1 Glanadh
Sguab an inneal le clò bog, tioram. Na cleachd innealan-glanaidh sgrìobach no fuasglaidhean, oir dh’fhaodadh iad milleadh a dhèanamh air a’ ch.asing no sgrion.
6.2 Cùram Bataraidh
To prolong battery life, avoid fully discharging the device frequently. Recharge the battery when the low battery indicator appears. If storing the device for an extended period, charge it to approximately 50% every few months.
6.3 Stòradh
Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Keep it away from strong magnetic fields.
7. A ’dèanamh trioblaid
| Trioblaid | Adhbhar a dh’fhaodadh a bhith ann | Fuasgladh |
|---|---|---|
| Chan eil cumhachd aig an inneal. | Bataraidh ìosal no mearachd inneil. | Cuir cosgais air an inneal airson co-dhiù 30 mionaid. Mura tòisich e fhathast, cuir fios chun taic. |
| Leughaidhean neo-mhearachdach. | Interference from other electronic devices or incorrect unit settings. | Move away from potential sources of electromagnetic interference. Verify the correct measurement unit is selected in settings. |
| Chan eil an inneal-rabhaidh a’ fuaimneachadh/a’ crith. | Alarm thresholds not set or alarm mode disabled. | Check alarm settings and ensure desired alarm modes (sound, vibrate, light) are enabled. |
| Tha an scrion bàn no reòta. | Mearachd bathar-bog. | Press and hold the power button for 10-15 seconds to force a restart. If the issue persists, contact support. |
