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.
- Maitinimas: Press the power button to turn on the device. A self-test may occur.
4. Naudojimo instrukcijos
4.1. NJTY T3 Digital Multimeter Operation
The multimeter features an auto-function scan for ease of use.
- Maitinimo įjungimas/išjungimas: 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.
- AC/DC matavimas Voltage: Prijunkite bandymo laidus prie grandinės arba komponento, kad išmatuotumėte tūrįtage. The display will show the reading.
- Tęstinumo testas: 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.
- Atsparumo matavimas: Prijunkite bandymo laidus prie komponento, kad išmatuotumėte jo varžą.
- NCV (Non-Contact Voltage) Aptikimas: Move the top of the multimeter near an AC voltage source. The device will indicate the presence of voltage be tiesioginio kontakto.
- Duomenų sulaikymas: Norėdami užfiksuoti dabartinį rodmenį ekrane, paspauskite mygtuką „HOLD“. Norėdami atleisti, paspauskite dar kartą.
- Žibintuvėlis / foninis apšvietimas: The multimeter includes a built-in flashlight and backlight for improved visibility in dark environments.

4.2. NJTY Non-Contact Voltage Tester Operation
Ttage tester is designed for quick and safe voltage aptikimas.
- NCV (Non-Contact Voltage) Aptikimas: 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.
- Jautrumo reguliavimas: 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. Priežiūra
- Valymas: Wipe the devices with a dry, clean cloth. Do not use abrasive cleaners or solvents.
- Saugykla: 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. Problemų sprendimas
- Įrenginys neįsijungia: 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.
- Operacija su pertraukomis: Check for loose connections or low battery.
