2. Enfòmasyon sou Sekirite
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.
- Pa sèvi ak aparèy tès la si li sanble domaje oswa si li pa fonksyone byen.
- 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.
- Pa depase vol espesifye atage 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.
- Do not use the device in wet conditions or in explosive atmospheres.
- The integrated laser pointer should not be aimed directly at eyes or reflective surfaces.

- Probe (NCV Sensor Head): Detekte AC voltage san kontak.
- Lazè konsèy: Emits a red laser for targeting test points.
- Flach: Bay ekleraj nan kondisyon ki pa twò klere.
- Signal / Indicator: Endikasyon vizyèl volim nantage deteksyon.
- High/Low Signal Indicator: Displays the detected voltage nivo.
- Bouton pouvwa: Limen ak etenn aparèy la.
- Sensitivity Switch (H/L): Chanje ant mòd sansiblite wo ak ba.
- Lighting / Laser Switch: Activates the flashlight or laser pointer.
- Kouvèti batri: Access point for battery replacement.
4. Enstalasyon
4.1 Enstalasyon batri
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).
- Mete de pil AAA 1.5V, asire w polarite a kòrèk (+/-).
- Replace the battery cover and screw it securely.

5. Operasyon Enstriksyon
5.1 Power On/Off
- Pou pouvwa sou, peze epi kenbe la Bouton pouvwa (refer to Image 2, item 6) until the indicator lights illuminate.
- Pou koupe pouvwa a, peze epi kenbe Bouton pouvwa 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) pou chwazi mòd sa a.
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 Voltage (NCV) Deteksyon
Pou detekte vòl AC atage:
- Turn on the tester and select the desired sensitivity mode.
- Mete la Probe (NCV Sensor Head) near the conductor, outlet, or device you wish to test.
- Si AC 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.
- Deplase la 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 Flach
To activate the integrated LED flashlight for illuminating dark work areas:
- Peze a Lighting / Laser Switch (refer to Image 2, item 8) once.
- Press it again to turn off the flashlight.

5.6 Lazè Pointer
To activate the laser pointer for precise targeting:
- Peze epi kenbe la Lighting / Laser Switch (refer to Image 2, item 8) for a few seconds.
- Release the button to turn off the laser pointer.
- Atansyon: Do not stare into the laser beam or point it at people or animals.

6. Antretyen
- Netwayaj: Siye aparèy la avèk yon twal sèk epi mou. Pa sèvi ak pwodui netwayaj abrazif oswa solvan.
- Depo: Store the tester in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
- Ranplasman batri: Ranplase pil yo byen vit lè endikatè pil fèb la parèt pou asire lekti yo egzak.
NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Tèstè a pa limen. | Pil ki mouri oswa ki mal enstale. | Tcheke polarite pil yo; ranplase pil yo. |
| No detection on a known live circuit. | Low battery, incorrect sensitivity mode, or device malfunction. | Replace batteries, switch to high sensitivity mode (12V-1000V), or contact customer support. |
| False positives (detects voltage kote pa genyen). | High sensitivity mode in a noisy electrical environment. | Switch to low sensitivity mode (48V-1000V). |
