2. Varnostne informacije
Always adhere to local safety regulations and practices when working with electricity. This device is designed to enhance safety, but it does not replace proper electrical safety procedures. Failure to follow these instructions may result in electric shock, injury, or death.
- Testerja ne uporabljajte, če je videti poškodovan ali če ne deluje pravilno.
- Verify the tester's functionality on a known live circuit before and after each use.
- Always wear appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses.
- Ne prekoračite navedene količinetage range (12V-1000V AC or 48V-1000V AC).
- Keep fingers behind the finger guard during operation.
- Avoid direct contact with live conductors. This is a non-contact device.
- Naprave ne uporabljajte v mokrih pogojih ali v eksplozivnih atmosferah.
- The integrated laser pointer should not be aimed directly at eyes or reflective surfaces.

- Sonda (glava senzorja NCV): Zazna AC voltage brez kontakta.
- Laserski kazalec: Emits a red laser for targeting test points.
- Svetilka: Zagotavlja osvetlitev v slabih svetlobnih pogojih.
- Signal / Indicator: Vizualni prikaz volumnatage zaznavanje.
- High/Low Signal Indicator: Displays the detected voltage ravni.
- Gumb za vklop: Vklopi in izklopi napravo.
- Sensitivity Switch (H/L): Toggles between high and low sensitivity modes.
- Lighting / Laser Switch: Activates the flashlight or laser pointer.
- Pokrov baterije: Access point for battery replacement.
4. Nastavitev
4.1 Namestitev baterije
The NJTY Voltage Tester requires two AAA batteries (included). To install or replace batteries:
- Unscrew the battery cover at the bottom of the tester (refer to Image 2, item 9).
- Vstavite dve bateriji 1.5 V AAA in pazite na pravilno polarnost (+/-).
- Replace the battery cover and screw it securely.

5. Navodila za uporabo
5.1 Vklop/izklop
- Za vklop pritisnite in držite Gumb za vklop (refer to Image 2, item 6) until the indicator lights illuminate.
- Za izklop pritisnite in držite tipko Gumb za vklop again. The device will also automatically shut down after five minutes of inactivity to conserve battery life.
5.2 Sensitivity Modes
The tester features two sensitivity modes for different applications:
- High Sensitivity Mode (12V-1000V AC): Suitable for detecting lower voltages or for general detection. Press the Sensitivity Switch (H/L) (refer to Image 2, item 7) to select this mode.
- Low Sensitivity Mode (48V-1000V AC): Ideal for detecting higher voltages or when precise localization is needed to avoid false positives from adjacent wires. Press the Sensitivity Switch (H/L) da izberete ta način.
Image 4: Comparison of high and low sensitivity modes. The top row shows high sensitivity (12-1000V) detecting live wire and null wire. The bottom row shows low sensitivity (48-1000V) detecting live wire and null wire, demonstrating how the tester indicates voltage presence with visual and audible alerts.
5.3 brezkontaktna zvtage (NCV) zaznavanje
Za zaznavanje glasnosti izmeničnega tokatage:
- Turn on the tester and select the desired sensitivity mode.
- Postavite Probe (NCV Sensor Head) near the conductor, outlet, or device you wish to test.
- Če je voltage is detected, the tester will emit an audible alarm and the Signal / Indicator lights will illuminate, with the High/Low Signal Indicator showing the relative strength of the detected field.

5.4 Breakpoint Testing
This feature helps locate breaks in live wires:
- Ensure the wire is live and the tester is in an appropriate sensitivity mode.
- Premakni Probe (NCV Sensor Head) along the length of the wire.
- The tester will indicate voltage up to the point of the break. The absence of a signal beyond a certain point indicates a break in the circuit.
Image 6: Illustration of breakpoint testing. The tester indicates voltage on one side of a broken wire, and no voltage on the other side, pinpointing the location of the break.
5.5 Svetilka
To activate the integrated LED flashlight for illuminating dark work areas:
- Pritisnite Lighting / Laser Switch (refer to Image 2, item 8) once.
- Press it again to turn off the flashlight.

5.6 Laserski kazalec
To activate the laser pointer for precise targeting:
- Pritisnite in držite Lighting / Laser Switch (refer to Image 2, item 8) for a few seconds.
- Release the button to turn off the laser pointer.
- Pozor: Do not stare into the laser beam or point it at people or animals.

6. Vzdrževanje
- Čiščenje: Napravo obrišite s suho, mehko krpo. Ne uporabljajte abrazivnih čistil ali topil.
- Shranjevanje: Tester shranjujte na hladnem in suhem mestu, stran od neposredne sončne svetlobe in ekstremnih temperatur. Če ga shranjujete dlje časa, odstranite baterije, da preprečite puščanje.
- Zamenjava baterije: Ko se prikaže indikator nizke temperature baterije, takoj zamenjajte baterije, da zagotovite natančne odčitke.
