3.2. NJTY Non-Contact Voltage Tester Setup
The Non-Contact Voltage Tester is typically powered by internal batteries. Ensure they are properly installed or charged if rechargeable.
- Вклучување: Press the power button to turn on the device. A self-test may occur.
4. Упатства за работа
4.1. NJTY T3 Digital Multimeter Operation
The multimeter features an auto-function scan for ease of use.
- Вклучување/исклучување: Press and hold the power button to turn the multimeter on or off.
- Auto Function Scan: The multimeter automatically detects the type of measurement (AC/DC voltage, resistance, continuity) when the test leads are connected to a circuit.
- Мерење AC/DC Voltage: Connect the test leads across the circuit or component to measure voltage. The display will show the reading.
- Тест за континуитет: In continuity mode, the multimeter will emit an audible beep if the resistance between the two test points is below approximately 50Ω, indicating a continuous circuit.
- Мерење на отпор: Поврзете ги мерните сонди преку компонентата за да го измерите нејзиниот отпор.
- NCV (Без-контакт томtagд) Детекција: Поместете го горниот дел од мултиметарот во близина на јачината на звукот на наизменичната струја.tagизвор. Уредот ќе покаже присуство на волуменtagд без директен контакт.
- Задржување на податоци: Притиснете го копчето „ЗАДРЖИ“ за да го замрзнете тековното отчитување на екранот. Притиснете повторно за да го ослободите.
- Flashlight/Backlight: The multimeter includes a built-in flashlight and backlight for improved visibility in dark environments.

4.2. NJTY Non-Contact Voltage Tester Operation
Волtage tester is designed for quick and safe voltagд откривање.
- NCV (Без-контакт томtagд) Детекција: Place the tip of the tester near a wire or outlet. The device will indicate the presence of AC voltage through visual and audible alerts.
- Прилагодување на чувствителност: The tester offers dual sensitivity ranges (12-1000V and 48-1000V). Use the sensitivity button to switch between low and high sensitivity modes as needed for different applications.
- Live/Neutral Wire Identification: The tester uses voice alerts to audibly distinguish between live (hot) and neutral wires, enhancing safety and ease of identification.
- Break-Point Test: Use the tester to identify breaks in wires or cables. Move the tester along the wire; the absence of a signal indicates a break.
- Flashlight & Laser: The tester includes a built-in flashlight for illuminating work areas and a laser for precise alignment or pointing.

5. Одржување
- Чистење: Wipe the devices with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Складирање: Store the bundle in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care (Multimeter): Recharge the multimeter regularly, especially if it will not be used for an extended period, to maintain battery health.
6 Смена на проблеми
- Уредот не се вклучува: Ensure the battery is charged (Multimeter) or properly installed (Voltage Tester).
- Inaccurate Readings (Multimeter): Check test lead connections. Ensure the correct measurement mode is selected (though auto-scan helps).
- No Detection (Voltage Tester): Ensure the device is powered on. Adjust sensitivity if necessary.
- Наизменична операција: Проверете дали има лабави врски или слаба батерија.
