3. Nastavitev
3.1. NJTY T3 Digital Multimeter Setup
The NJTY T3 Digital Multimeter features a built-in rechargeable battery. Before first use, ensure the device is fully charged.
- Polnjenje: Connect the multimeter to a standard USB power source using the provided Type-C USB cable. The charging indicator will illuminate.
- Testni vodi: Insert the red test lead into the 'VΩmA' input jack and the black test lead into the 'COM' input jack. Ensure a secure connection.

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.
- Vklop: Press the power button to turn on the device. A self-test may occur.
4. Navodila za uporabo
4.1. NJTY T3 Digital Multimeter Operation
The multimeter features an auto-function scan for ease of use.
- Vklop/izklop: 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.
- Merjenje AC/DC Voltage: Connect the test leads across the circuit or component to measure voltage. The display will show the reading.
- Test kontinuitete: 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.
- Merjenje upora: Za merjenje upornosti komponente priključite merilne kable.
- NCV (brezkontaktna voltage) Zaznavanje: Move the top of the multimeter near an AC voltage source. The device will indicate the presence of voltage brez neposrednega stika.
- Zadrževanje podatkov: Pritisnite gumb »HOLD«, da zamrznete trenutno odčitavanje na zaslonu. Za sprostitev pritisnite znova.
- 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
Voltage tester is designed for quick and safe voltage zaznavanje.
- NCV (brezkontaktna voltage) Zaznavanje: 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.
- Prilagoditev občutljivosti: 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. Vzdrževanje
- Čiščenje: Naprave obrišite s suho, čisto krpo. Ne uporabljajte abrazivnih čistil ali topil.
- Shranjevanje: 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. Odpravljanje težav
- Naprava se ne vklopi: 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.
- Občasno delovanje: Preverite, ali so povezave ohlapne ali baterija prazna.
