5. Kullanım Talimatları
5.1 Güç Açma/Kapatma
Kırmızıya basın Anahtar Düğmesi Cihazı açmak veya kapatmak için.
5.2 Basic Light Measurement
- Turn on the light meter.
- Ensure the light detector is clean and free from obstructions.
- Point the light detector towards the light source or area where you want to measure illuminance. The sensor can be rotated up to 270° left and 90° right for optimal positioning.
- The current illuminance value will be displayed on the LCD screen in Lux or FC units.

5.3 Unit Selection (Lux/FC, °C/°F)
Basın MOD button to toggle between Lux and FC units for light measurement. Long press the MOD button to switch between Celsius (°C) and Fahrenheit (°F) for temperature display.
5.4 Veri Tutma
Basın TUTMAK key briefly to freeze the current reading on the display. Press it again to release the hold function and resume live measurement.
5.5 Max/Min Data Hold
Basın MAKSİMUM/MİNİMUM key to cycle through the maximum, minimum, and current readings. The display will indicate 'MAX' or 'MIN' when these values are shown.
5.6 Data Storage (REC)
Kısa basın KAYIT button to record the current data. Long press the KAYIT düğmesini kullanın, ardından REL/UP anahtar view saklanan veriler.

5.7 Auto/Manual Ranging
The device typically operates in auto-ranging mode. To switch to manual ranging, long press the HOLD/RANGE key. Press again to select different ranges. Long press again to return to auto-ranging.
5.8 Relative Value Measurement
Basın REL/UP key to enter relative value mode. The meter will display the difference between the current measurement and a set reference value.
6. Bakım
- Temizlik: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the light detector is kept clean for accurate readings.
- Depolamak: When not in use for extended periods, remove the battery to prevent leakage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
- Sensör Koruması: Keep the protective cap on the light sensor when not in use to prevent damage and dust accumulation.
7. Sorun Giderme
- Cihaz açılmıyor: Pilinin doğru takılıp takılmadığını ve yeterli şarjı olup olmadığını kontrol edin. Gerekirse pili değiştirin.
- Yanlış okumalar: Ensure the light detector is clean and unobstructed. Verify that the correct measurement unit (Lux/FC) is selected. Check for strong electromagnetic interference nearby.
- Display shows 'OL' (Over-range): The measured light intensity exceeds the current range. If in manual ranging mode, switch to a higher range. If in auto-ranging, the light intensity is beyond the device's maximum capacity.
- Ekran soluk veya titriyor: Pil zayıf olabilir. Pili değiştirin.
