2. Informazioni sulla sicurezza
Always prioritize safety when working with electrical systems. Read and understand all safety warnings before using the VT200 voltagetester.
- LA SICUREZZA PRIMA: The VT200 provides multiple alarms (sound and light) to indicate voltage presence. A red light and beep indicate high voltage. Higher frequency beeps and red light indicate closer proximity to the voltage source or higher voltage. Green light indicates low voltage or null wire.
- SECURITY LEVEL: This device is IEC rated CAT III 1000V and CAT IV 600V, and meets CE certification standards. It is safely double insulated.
- Alto volumetage Avviso: An alert is triggered for voltages above 90V, indicated by a red light and continuous beeping.
- Always test on a known live circuit before and after use to confirm the tester is functioning correctly.
- Do not use the tester if it appears damaged or is not operating properly.
- Keep hands and fingers away from the tip of the tester during operation.
- Questo dispositivo è per AC voltage detection only. Do not use for DC voltage.
3. Caratteristiche del prodotto
The KAIWEETS VT200 is equipped with several features to enhance its functionality and user experience:
- Non-Contact Detection (NCV): Rileva in modo sicuro la tensione CAtage by simply placing the tip near a terminal strip, outlet, or supply cord. The tester will indicate voltage presence without physical contact.
- Sensibilità a doppia gamma: Detects both standard (48-1000V AC) and low voltage (12-1000V AC) for versatile applications. The NCV sensor automatically recognizes the voltage and displays it on a bar graph.
- Rilevamento del filo fase/neutro: il volumetage detector can automatically distinguish between live and neutral wires.
- Test del punto di interruzione: Ideal for identifying breakpoints in wires and cables. Use high-sensitivity mode for this function.
- Torcia LED integrata: A bright LED flashlight assists in working in dimly lit areas.
- Indicatore di basso consumo: Avvisi quando il livello della batteria è bassotage scende sotto i 2.5 V.
- Spegnimento automatico: The device automatically powers off after 3 minutes of inactivity or no signal detection to conserve battery life.
- Compact Design with Pen Hook: Easy to carry in a shirt pocket for convenience.

4. Impostazione
4.1 Installazione della batteria
The KAIWEETS VT200 requires 2 AAA batteries (included). Follow these steps to install or replace batteries:
- Locate the battery compartment cap at the top of the tester.
- Twist or slide the cap to open the battery compartment.
- Inserire due batterie AAA, assicurandosi che la polarità sia corretta (+/-) come indicato all'interno del vano.
- Chiudere saldamente il coperchio del vano batteria.

5. Istruzioni per l'uso
5.1 Accensione/spegnimento
- To power on, press the red power button (⏻). The indicator lights will briefly illuminate.
- To power off, press and hold the red power button (⏻) for approximately 2 seconds. The device will also auto-off after 3 minutes of inactivity.
5.2 Adjusting Sensitivity (Dual Range)
- The VT200 has two sensitivity ranges: 48V-1000V AC (Low Sensitivity) and 12V-1000V AC (High Sensitivity).
- Premere il pulsante verde 'S' (S) to toggle between sensitivity modes.
- Use the low sensitivity range for general voltage detection in outlets or main wires.
- Switch to high sensitivity for detecting lower voltages or for applications like doorbells, thermostats, irrigation wiring, or breakpoint testing.

Figure 11: Sensitivity Button
5.3 Senza contatto voltage (NCV) Test
- Assicurarsi che il tester sia acceso.
- Posizionare la punta del tester vicino al filo, alla presa o al componente elettrico che si desidera testare.
- The tester will emit beeps and illuminate its indicator lights based on the detected voltage:
- Red Light & Beeping: Indica volume elevatotage or live wire detected. The frequency of beeps increases with higher voltage or closer proximity.
- Luce verde: Indica basso volumetage or null wire detected.

5.4 Breakpoint Finding
Per individuare un punto di interruzione in un filo:
- Switch the tester to high sensitivity mode (12V-1000V AC).
- Slowly move the tip of the tester along the wire.
- Il tester indicherà il volumetage up to the point of the break. The alarm will stop or significantly reduce past the breakpoint.
5.5 Utilizzo della torcia a LED
- Press the green flashlight button (often integrated with the 'S' button) to turn the LED flashlight on or off.
- The flashlight is useful for illuminating dark work areas like electrical panels or behind appliances.
6. Manutenzione
6.1 Sostituzione della batteria
When the low-power indicator illuminates, it's time to replace the batteries. Refer to Section 4.1 for battery installation instructions.
6.2 Pulizia
- Wipe the exterior of the tester with a clean, damp stoffa.
- Non utilizzare detergenti abrasivi o solventi.
- Ensure the tester is completely dry before storage or next use.
6.3 Conservazione
- Conservare il tester in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
- If storing for extended periods, it is recommended to remove the batteries to prevent leakage.
7. Risoluzione Dei Problemi
If you encounter issues with your VT200 voltage tester, refer to the following common problems and solutions:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il tester non si accende. | Batterie scariche o installate in modo errato. | Sostituire le batterie assicurandosi che la polarità sia corretta. |
| No indication when testing a live circuit. | Tester is off, batteries are low, or sensitivity is too low. | Ensure tester is on. Check/replace batteries. Switch to high sensitivity mode. Test on a known live circuit. |
| False positives (tester indicates voltage dove non esiste). | High sensitivity in an electromagnetically noisy environment. | Switch to low sensitivity mode. Move away from strong electromagnetic fields. |
| La torcia non funziona. | Le batterie sono scariche o quasi scariche. | Sostituire le batterie. |
