5. Opsætning
5.1 Batteriinstallation
The TM-213 requires two 1.5V AAA batteries for operation. Batteries are not included with the device.
- Find batteridækslet på bagsiden af måleren.
- Brug en lille skruetrækker til at løsne skruen, der fastgør batteridækslet.
- Fjern batteridækslet.
- Isæt to 1.5V AAA-batterier, og overhold den korrekte polaritet (+/-) som angivet inde i batterirummet.
- Sæt batteridækslet på igen, og spænd skruen godt fast.

5.2 Tænd/sluk
- To turn the meter ON, press the green Power button (●).
- To turn the meter OFF, press the green Power button (●) igen.
- The meter features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.
6. Betjeningsvejledning
6.1 Tage en måling
- 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 NUL 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 Ændring af måleenheder
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Tryk på ENHED button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
6.3 Dataholdefunktion
Sådan fryser du den aktuelle aflæsning på displayet:
- Tryk på HOLDE button during a measurement. The reading will be frozen.
- Tryk på HOLDE knappen igen for at afslutte aflæsningen og genoptage livemålingen.
7. Vedligeholdelse
7.1 Rengøring
- Tør målerens c afasing med en blød, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- 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 Opbevaring
- 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.
- Hvis produktet opbevares i længere tid, skal batterierne fjernes for at forhindre lækage.
- Opbevares på et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer.
