2. Informazioni sulla sicurezza
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 è aperto.
- Avoid exposing the meter to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Non tentare di riparare o modificare il misuratore. Per qualsiasi intervento di assistenza, rivolgersi a personale qualificato.
- Remove batteries if the meter is not to be used for an extended period to prevent battery leakage.
- Keep the sensor clean and free from obstructions for accurate readings.
- 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.

4.1 Comandi e display
- Schermo LCD: Mostra le letture delle misurazioni, le unità e altri indicatori.
- Pulsante di accensione (●): Accende o spegne il misuratore.
- Pulsante ZERO: Used to zero the reading before measurement.
- Pulsante UNITÀ: Toggles between measurement units (uW/cm² and mW/cm²).
- Pulsante ATTESA: Blocca la lettura corrente sul display.
- Sensore UV: Detects UVAB radiation. Ensure it is clean and unobstructed.
5. Impostazione
5.1 Installazione della batteria
The TM-213 requires two 1.5V AAA batteries for operation. Batteries are not included with the device.
- Individuare il coperchio del vano batterie sul retro del misuratore.
- Use a small screwdriver to loosen the screw securing the battery cover.
- Rimuovere il coperchio della batteria.
- Inserire due batterie AAA da 1.5 V, rispettando la polarità corretta (+/-) come indicato all'interno del vano.
- Riposizionare il coperchio della batteria e serrare saldamente la vite.

5.2 Accensione/Spegnimento
- To turn the meter ON, press the green Power button (●).
- To turn the meter OFF, press the green Power button (●) Ancora.
- The meter features an automatic shutdown function after approximately 15 minutes of inactivity to conserve battery life.
6. Istruzioni per l'uso
6.1 Esecuzione di una misurazione
- Ensure batteries are installed and the meter is powered ON.
- Remove the protective cap from the UV sensor.
- Azzeramento del misuratore: 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 Modifica delle unità di misura
The TM-213 can display readings in microwatts per square centimeter (uW/cm²) or milliwatts per square centimeter (mW/cm²).
- Premere il tasto UNITÀ button to toggle between uW/cm² and mW/cm².
- Note that 1000 uW/cm² is equivalent to 1 mW/cm².
6.3 Funzione di conservazione dei dati
Per bloccare la lettura corrente sul display:
- Premere il tasto PRESA button during a measurement. The reading will be frozen.
- Premere il tasto PRESA nuovamente il pulsante per annullare la lettura e riprendere la misurazione in tempo reale.
7. Manutenzione
7.1 Pulizia
- Pulisci il contatore casing con un morbido, damp panno. Non usare detergenti abrasivi o solventi.
- 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 Conservazione
- 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.
- Se si conserva il prodotto per un periodo prolungato, rimuovere le batterie per evitare perdite.
- Conservare in un luogo fresco e asciutto, lontano dalla luce solare diretta e dalle temperature estreme.

8. Risoluzione Dei Problemi
If you encounter issues with your TM-213 meter, refer to the table below for common problems and solutions.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il misuratore non si accende. | Batterie scariche o installate in modo errato. | Controllare la polarità della batteria. Sostituirla con batterie AAA da 1.5 V nuove. |
| Il display mostra "OL". | Overload condition; UV radiation exceeds the meter's range. | Move the meter further from the UV source or use in a lower intensity environment. |
| Letture imprecise o fluttuanti. | Dirty sensor, improper zeroing, or external interference. | Clean the UV sensor. Perform a zero calibration in a dark environment. Ensure no strong electromagnetic fields are nearby. |
| Meter shuts off unexpectedly. | Automatic shutdown activated or low battery. | This is normal after 15 minutes of inactivity. If it happens during use, replace batteries. |
