2. Sigurnosne informacije
To ensure safe operation and to prevent damage to the meter, please observe the following safety precautions:
- Do not operate the meter if it appears damaged or if the casing je otvoren.
- Izbjegavajte izlaganje mjerača ekstremnim temperaturama, vlazi ili direktnoj sunčevoj svjetlosti tokom dužeg perioda.
- Do not attempt to repair or modify the meter. Refer all servicing to qualified personnel.
- Remove batteries if the meter is not to be used for an extended period to prevent battery leakage.
- Održavajte senzor čistim i bez prepreka kako biste dobili tačna očitavanja.
- This device measures UV radiation. Prolonged exposure to high levels of UV radiation can be harmful. Use appropriate personal protective equipment when working in environments with high UV levels.

5. Podešavanje
5.1 Instalacija baterije
The TM-213 requires two 1.5V AAA batteries for operation. Batteries are not included with the device.
- Pronađite poklopac odjeljka za baterije na stražnjoj strani mjerača.
- Use a small screwdriver to loosen the screw securing the battery cover.
- Skinite poklopac baterije.
- Umetnite dvije AAA baterije od 1.5 V, pazeći na ispravan polaritet (+/-) kao što je naznačeno unutar odjeljka.
- Vratite poklopac baterije i čvrsto pritegnite zavrtanj.

5.2 Uključivanje/isključivanje
- To turn the meter ON, press the green Power button (●).
- To turn the meter OFF, press the green Power button (●) ponovo.
- The meter features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.
6. Uputstvo za upotrebu
6.1 Mjerenje
- Ensure batteries are installed and the meter is powered ON.
- Remove the protective cap from the UV sensor.
- Zeroing the Meter: In an area with no UV light (e.g., in a dark room or with the sensor completely covered), press the NULA 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 Promjena mjernih jedinica
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Pritisnite JEDINICA button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
6.3 Funkcija zadržavanja podataka
Da biste zamrznuli trenutno očitanje na ekranu:
- Pritisnite HOLD button during a measurement. The reading will be frozen.
- Pritisnite HOLD ponovo pritisnite dugme da biste otpustili očitanje i nastavili mjerenje uživo.
7. Održavanje
7.1 Čišćenje
- Obrišite c mjeračaasing s mekim, damp tkanina. Nemojte koristiti abrazivna sredstva za čišćenje ili rastvarače.
- 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 Skladištenje
- 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.
- Ako skladištite duže vrijeme, izvadite baterije kako biste spriječili curenje.
