5.2 Menghidupkan/Mematikan
- To turn the meter ON, press the green Power button (●).
- To turn the meter OFF, press the green Power button (●) lagi.
- The meter features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.
6. Arahan Operasi
6.1 Mengambil Pengukuran
- Ensure batteries are installed and the meter is powered ON.
- Remove the protective cap from the UV sensor.
- Sifar Meter: In an area with no UV light (e.g., in a dark room or with the sensor completely covered), press the SIFAR button. The display should show "0" or a value very close to zero. This step ensures accuracy.
- Position the UV sensor towards the UV source or area you wish to measure.
- Read the UV radiation value displayed on the LCD screen. The measurement updates approximately every 3 seconds.
6.2 Menukar Unit Pengukuran
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Tekan ke UNIT button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
6.3 Fungsi Pegangan Data
Untuk membekukan bacaan semasa pada paparan:
- Tekan ke TAHAN button during a measurement. The reading will be frozen.
- Tekan ke TAHAN butang sekali lagi untuk melepaskan bacaan dan menyambung semula pengukuran langsung.
7. Penyelenggaraan
7.1 Pembersihan
- Lap meter casing dengan lembut, damp kain. Jangan gunakan pembersih atau pelarut yang melelas.
- Keep the UV sensor clean and free of dust or debris. Use a soft, lint-free cloth to gently clean the sensor surface.
7.2 Penyimpanan
- When not in use, always place the protective cap over the UV sensor.
- Store the meter in its carrying case to protect it from dust, moisture, and physical damage.
- Jika menyimpan untuk tempoh yang lama, keluarkan bateri untuk mengelakkan kebocoran.
- Simpan di tempat yang sejuk dan kering jauh dari cahaya matahari langsung dan suhu yang melampau.
