5.2 Engegada/apagada
- To turn the meter ON, press the green Power button (●).
- To turn the meter OFF, press the green Power button (●) de nou.
- The meter features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.
6. Instruccions de funcionament
6.1 Prendre una mesura
- Ensure batteries are installed and the meter is powered ON.
- Remove the protective cap from the UV sensor.
- Posar a zero el comptador: In an area with no UV light (e.g., in a dark room or with the sensor completely covered), press the ZERO 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 Canvi d'unitats de mesura
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Premeu el botó UNITAT button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
6.3 Funció de retenció de dades
Per congelar la lectura actual a la pantalla:
- Premeu el botó MANTENIM durant una mesura. La lectura es congelarà.
- Premeu el botó MANTENIM button again to release the reading and resume live measurement.
7. Manteniment
7.1 Neteja
- Netegeu la c del comptadorasing amb un suau, damp tela. No utilitzeu netejadors abrasius ni dissolvents.
- 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 Emmagatzematge
- 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.
- Si l'emmagatzemeu durant un període prolongat, traieu les piles per evitar fuites.
