Instruccions de funcionament
Encès/Apagat
- Press the Power Button (marked with a circle and vertical line) to turn the device on. The indicator lights will briefly flash.
- Press and hold the Power Button again to turn the device off.
Ajust de sensibilitat
- Press the H/L button to toggle between High Sensitivity (AC12-1000V) and Low Sensitivity (AC48-1000V) modes.
- Use High Sensitivity for detecting lower voltages or for detecting voltage through insulation.
- Use Low Sensitivity for detecting higher voltages or for more precise localization of voltage fonts.
Vol. ACtage Detecció
- Turn on the device and select the desired sensitivity mode.
- Bring the NCV Probe (tip of the pen) close to the object you wish to test (e.g., wire, outlet, circuit breaker).
- Si AC voltage is detected, the Alarm Indicator LEDs will light up, and the Buzzer will sound.
- The intensity of the light and the frequency of the beep indicate the signal strength: a weak signal results in a slow beep and yellow light, while a strong signal results in a rapid beep and red light.

Zero Line and Fire Line Judgment
- When testing an AC outlet or wire, the backlight color of the detector will change to indicate the line type.
- A yellow backlight indica el Línia Zero.
- A red backlight indica el Fire Line.
Flashlight and Laser Indicator
- Press the Flashlight/Red Light Control button to activate the white LED flashlight for illumination in dark areas.
- Press the button again to activate the red laser indicator for pointing.
- Press a third time to activate both the flashlight and laser.
- Press a fourth time to turn both off.

Manteniment
- Mantingueu el dispositiu net i sec. Netegeu-lo amb un drap suau i sec.amp drap si cal. No utilitzeu productes de neteja abrasius ni dissolvents.
- Traieu les piles si no heu d'utilitzar el dispositiu durant un període prolongat per evitar fuites.
- Guardeu el dispositiu en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
- No intenteu obrir ni modificar el dispositiu, ja que això anul·larà la garantia i pot suposar un risc per a la seguretat.
Resolució de problemes
- El dispositiu no s'encén: Check if the batteries are installed correctly and are not depleted. Replace batteries if necessary.
- No detection when voltage està present: Ensure the device is turned on and the NCV probe is close enough to the voltage source. Try switching to High Sensitivity mode.
- False positives/detection in unexpected areas: Switch to Low Sensitivity mode for more precise detection. Ensure there are no other strong electrical fields nearby that could interfere.
- Is the device suitable for DC voltage? No, the NJTY T02 is specifically designed for AC voltage detection (12-1000V AC) and should not be used for DC circuits.
- Can the laser detect voltage from a distance? No, the laser indicator is for pointing only. The non-contact voltage detection feature relies on proximity to the AC source.
Consells per a l'usuari
- Many users find this tool very convenient for quickly identifying live wires and distinguishing between phase (live) and neutral (zero) lines, making electrical work safer and more efficient.
- The compact size and portable hook make it easy to carry in a pocket or tool belt, ensuring it's always available when needed.
- Utilize the built-in flashlight when working in dimly lit areas to improve visibility and safety.
