2. FLIR VP50-2 CAT IV Voltage Rivelatore
2.1. Prodotto finitoview
The FLIR VP50-2 is a non-contact AC voltage detector designed for reliable voltage presence verification. It features a bright flashlight and provides both vibration and audio alarms to alert users to live AC voltage. Its robust design ensures durability in demanding work environments.
2.2 Caratteristiche
- Volume senza contattotage Rilevamento: Rileva AC voltage da 90V a 1000V senza contatto diretto.
- Audible and Vibrating Alarms: Provides clear alerts when voltage viene rilevato.
- Torcia integrata: Illumina le aree di lavoro buie per una migliore visibilità.
- Costruzione durevole: Resiste a cadute da altezze fino a 3 metri.
- Design ergonomico: Features an anti-roll case for comfortable handling.
- Basso-Profile Sonda: Allows access to tight spaces for wire mapping and circuit tracing.
2.3. Impostazione
Before first use, ensure the device is powered and functional.
- Installazione della batteria: Open the battery compartment (typically at the rear or base) and insert the required batteries, observing polarity.
- Accensione: Press the power button to turn on the detector. A green LED indicator should illuminate, indicating readiness.
- Test di autoverifica: The device performs a self-test upon power-on. Ensure no error indicators are present.

2.4. Istruzioni per l'uso
Follow these steps for safe and accurate voltage rilevamento:
- Accensione: Press the power button to activate the detector.
- Funzionamento della torcia: Press the flashlight button to turn the integrated flashlight on or off.
- Voltage Rilevamento: Place the tip of the detector near the wire, outlet, or electrical component you wish to test. If AC voltage is present within the detection range (90-1000V), the detector will emit an audible alarm and vibrate. A red LED indicator will also illuminate.
- Verify Absence of Voltage: Always test on a known live circuit first, then the circuit to be tested, and then re-test the known live circuit to confirm the detector is functioning correctly.

2.5. Manutenzione
- Pulizia: Wipe the detector with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Magazzinaggio: Conservare il dispositivo in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme. Rimuovere le batterie se si prevede di non utilizzarlo per periodi prolungati.
- Sostituzione della batteria: Replace batteries when the low battery indicator appears or the device fails to power on.
2.6. Risoluzione Dei Problemi
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il rilevatore non si accende. | Batterie scariche o installate in modo errato. | Sostituire le batterie assicurandosi che la polarità sia corretta. |
| No alarm when voltage è presente. | Batteria scarica; malfunzionamento del dispositivo. | Sostituisci le batterie. Se il problema persiste, contatta l'assistenza. |
| Falsi allarmi. | Forte interferenza elettromagnetica. | Move away from strong electrical fields; re-test. |
