2. Informazioni sulla sicurezza
Please read and understand all safety instructions before operating the HABOTEST HT103. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Si dà sempre per scontato che un circuito sia sotto tensione finché non viene dimostrato il contrario.
- Non utilizzare il dispositivo se appare danneggiato o non funziona correttamente.
- Prima dell'uso, assicurarsi che il vano batteria sia ben chiuso.
- Non tentare di misurare il voltages exceeding the specified range (AC 1000V).
- This device is designed for non-contact detection. Do not use it as a substitute for proper lockout/tagle nostre procedure.
- Mantieni il dispositivo asciutto e pulito.
- Replace batteries promptly when the low-battery indicator appears.

4. Impostazione
4.1 Installazione della batteria
The HABOTEST HT103 requires two 1.5V AAA batteries (not included).
- Unscrew the battery compartment cover at the top of the device.
- Inserire due batterie AAA da 1.5 V, assicurandosi della corretta polarità (+/-).
- Securely screw the battery compartment cover back into place.

5. Istruzioni per l'uso
5.1 Accensione/spegnimento
- Per accendere, premere il Tasto interruttore di alimentazione (⏻). The LCD will illuminate.
- Per spegnere, tenere premuto il pulsante Tasto interruttore di alimentazione (⏻) per circa 2 secondi.
5.2 volumitage rilevamento
The HT103 offers two sensitivity modes for AC voltage rilevamento:
- Low Sensitivity (Default): AC 70-1000V. Suitable for general household wiring and higher voltage applicazioni.
- Alta sensibilità: AC 12-1000V. Ideal for detecting lower voltages, such as those in low-voltage circuits or behind thicker insulation.
To switch sensitivity modes, briefly press the Sensitivity Switch Key (⌘). The display will indicate the current sensitivity setting.

Per rilevare voltage:
- Turn on the device and select the desired sensitivity.
- Place the NCV sensing head near the wire, cable, or electrical component you wish to test.
- Se AC voltage is detected, the device will emit a sound alarm (from slow to fast), the backlight will change from green to red, the signal indicator will flash, and the LCD will show a numerical percentage and analog bar graph indicating signal intensity.

5.3 Live and Neutral Wire Identification
Quando si rileva voltage, the LCD display will show a numerical percentage. Una percentuale più altatage indicates the live wire (fire line), while a lower percentage indicates the neutral wire (zero line).
5.4 Funzionamento della torcia
To activate the built-in LED flashlight, briefly press the Sensitivity Switch Key (⌘) once. Press it again to turn off the flashlight. This feature is useful for working in dimly lit areas.

6. Manutenzione
6.1 Pulizia
Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents. Ensure the device is dry before storage or use.
6.2 Sostituzione della batteria
When the low-battery indicator appears on the LCD, replace the batteries as described in the 'Battery Installation' section (4.1). Always use fresh 1.5V AAA batteries.
6.3 Conservazione
Conservare il dispositivo in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme. Se non lo si utilizza per un periodo prolungato, rimuovere le batterie per evitare perdite.
7. Risoluzione Dei Problemi
- Il dispositivo non si accende: Controllare l'installazione delle batterie e assicurarsi che non siano scariche. Sostituirle se necessario.
- Incoerente voltage rilevamento: Ensure the NCV sensing head is close enough to the conductor. Check for environmental interference. Try switching sensitivity modes.
- Indicatore di batteria scarica: Replace batteries immediately to ensure accurate readings and proper device function.
