4.1. NJTY T3 Digital Multimeter Operation

The multimeter features an auto-function scan for ease of use.

• Uključivanje/isključivanje: 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.
• Mjerenje AC/DC Voltage: Connect the test leads across the circuit or component to measure voltage. The display will show the reading.
• Test kontinuiteta: 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.
• Mjerenje otpora: Spojite mjerne kablove preko komponente kako biste izmjerili njen otpor.
• NCV (Non-Contact Voltage) Detekcija: Move the top of the multimeter near an AC voltage source. The device will indicate the presence of voltage bez direktnog kontakta.
• Zadržavanje podataka: Pritisnite dugme 'HOLD' da biste zamrznuli trenutno očitanje na ekranu. Pritisnite ponovo da biste ga otpustili.
• Svjetiljka/Pozadinsko osvjetljenje: 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 detekcija.

• NCV (Non-Contact Voltage) Detekcija: 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.
• Podešavanje osjetljivosti: 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.
• Identifikacija fazne/neutralne žice: 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. Održavanje

• čišćenje: Wipe the devices with a dry, clean cloth. Do not use abrasive cleaners or solvents.
• Skladištenje: 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. Otkrivanje problema

• Uređaj se ne uključuje: 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.
• Intermitentni rad: Check for loose connections or low battery.
