2. Информации за безбедност
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.
- Do not use the tester if it appears damaged or is not operating correctly.
- 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.
- Не надминувајте го наведениот волtage 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.

Image 2: Diagram illustrating the key components of the NJTY Voltage Tester. Labels include the NCV sensor head (probe), laser pointer, flashlight, signal/indicator lights, high/low signal indicator, power button, sensitivity switch (H/L), lighting/laser switch, and battery cover.
- Сонда (глава на сензорот NCV): Открива AC волtagд без контакт.
- Ласерски покажувач: Emits a red laser for targeting test points.
- Фенерче: Обезбедува осветлување во услови на слаба осветленост.
- Signal / Indicator: Визуелна индикација на волуменtagд откривање.
- High/Low Signal Indicator: Displays the detected voltagе ниво.
- Копче за вклучување: Го вклучува и исклучува уредот.
- Sensitivity Switch (H/L): Toggles between high and low sensitivity modes.
- Lighting / Laser Switch: Activates the flashlight or laser pointer.
- Капак за батерија: Access point for battery replacement.
4. Поставување
4.1 Инсталација на батерија
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).
- Вметнете две батерии од 1.5 V AAA, внимавајќи на точниот поларитет (+/-).
- Replace the battery cover and screw it securely.

5. Упатства за работа
5.1 Вклучување/исклучување
- За да го вклучите, притиснете и задржете го Копче за напојување (refer to Image 2, item 6) until the indicator lights illuminate.
- За да се исклучи, притиснете и задржете го Копче за напојување 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) за да го изберете овој режим.
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 Неконтактни томtage (NCV) Откривање
За откривање на AC волуменtage:
- Turn on the tester and select the desired sensitivity mode.
- Поставете го Probe (NCV Sensor Head) near the conductor, outlet, or device you wish to test.
- Ако 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.
- Премести го Probe (NCV Sensor Head) along the length of the wire.
- Тестерот ќе покаже волуменtage 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 фенерче
To activate the integrated LED flashlight for illuminating dark work areas:
- Притиснете го Lighting / Laser Switch (refer to Image 2, item 8) once.
- Press it again to turn off the flashlight.

5.6 Ласерски покажувач
To activate the laser pointer for precise targeting:
- Притиснете и задржете го Lighting / Laser Switch (refer to Image 2, item 8) for a few seconds.
- Release the button to turn off the laser pointer.
- Внимание: Do not stare into the laser beam or point it at people or animals.

6. Одржување
- Чистење: Избришете го уредот со сува, мека крпа. Не користете абразивни средства за чистење или растворувачи.
- Складирање: Чувајте го тестерот на ладно и суво место, подалеку од директна сончева светлина и екстремни температури. Доколку го чувате подолг период, извадете ги батериите за да спречите истекување.
- Замена на батерија: Заменете ги батериите веднаш кога ќе се појави индикаторот за слаба батерија за да се обезбедат точни мерења.
