Sigurnosne informacije

Always adhere to safety precautions when using any electrical testing equipment. Failure to do so may result in injury or damage to the device.

• Ne prekoračujte maksimalne ulazne vrijednosti navedene za svaku funkciju.
• Prije mjerenja provjerite jesu li mjerni kabeli u dobrom stanju i pravilno spojeni.
• Budite oprezni kada radite sa voltagiznad 30V AC RMS, 42V peak ili 60V DC, jer predstavljaju opasnost od strujnog udara.
• Ne koristite multimetar ako izgleda oštećeno ili ako je kućište otvoreno.
• Uvijek isključite napajanje testiranog strujnog kola prije mjerenja otpora ili kontinuiteta.
• Koristite beskontaktni Voltage (NCV) function as an initial check, but always verify with direct contact measurements when safety is critical.

Setup

1. Početno punjenje

The NJTY T3 Multimeter features a built-in rechargeable Lithium Ion battery. Before first use, or if the low battery indicator is displayed, charge the device using the provided Type-C charging cable.

1. Spojite kraj kabela za punjenje s Type-C priključkom na priključak za punjenje multimetra.
2. Connect the USB-A end of the charging cable to a standard USB power adapter (not included) or a computer's USB port.
3. The charging indicator on the multimeter will illuminate during charging and turn off when fully charged.

2. Povezivanje ispitnih vodova

Insert the red test lead into the "VΩ" input jack and the black test lead into the "COM" input jack. Ensure they are securely seated.

Uputstvo za upotrebu

The NJTY T3 Multimeter features an auto-ranging function, simplifying operation by automatically detecting the measurement type and range.

1. Uključivanje/isključivanje

Press and hold the power button to turn the multimeter on or off. The device will automatically shut off after approximately 15 minutes of inactivity to conserve battery life.

2. Automatic Measurement (Auto-Ranging)

In auto-ranging mode, the multimeter will automatically identify and measure AC voltage, DC voltage, or resistance when the test leads are applied to a circuit. The display will show the measurement type (AC, DC, Ω) and the value.

3. AC/DC Voltage Measurement

1. Ensure the multimeter is powered on.
2. Connect the test leads to the circuit points where voltage needs to be measured. The multimeter will automatically detect AC or DC voltage.
3. Pročitajte voltage vrijednost prikazana na ekranu.

4. Mjerenje otpora

1. Važno: Prije mjerenja otpora provjerite je li strujno kolo bez napona.
2. Connect the test leads across the component or circuit section where resistance is to be measured.
3. The multimeter will display the resistance value in Ohms (Ω), Kilo-Ohms (KΩ), or Mega-Ohms (MΩ).

5. Non-Contact Voltage (NCV) Detekcija

The NCV function allows for safe detection of live wires without direct contact.

1. Press the NCV button (if available, or ensure NCV mode is active).
2. Bring the NCV sensor at the top of the multimeter close to the wire or outlet.
3. The multimeter will emit an audible beep and the display will indicate the presence of AC voltage, with increasing intensity as it gets closer to the source.

6. Live Wire Testing

This function helps identify live wires in an AC circuit.

1. Insert the red test probe into the socket or touch it to the wire you want to test.
2. If the multimeter emits an alarm sound and the screen changes to indicate "LIVE", it signifies a live wire.

7. Test kontinuiteta

1. Važno: Prije izvođenja testa kontinuiteta provjerite je li strujni krug bez napona.
2. Connect the test leads across the component or wire to be tested.
3. If continuity exists (resistance is low, typically below 50Ω), the multimeter will emit an audible beep.

8. Zadržavanje podataka

Pritisnite dugme "HOLD" da biste zamrznuli trenutno očitanje na ekranu. Ponovo pritisnite da biste isključili funkciju zadržavanja.

9. Svjetiljka i pozadinsko osvjetljenje

The multimeter includes a built-in flashlight for illuminating the test area and a backlight for the display, enhancing visibility in low-light conditions. Refer to the device buttons for activation (typically a short press of the power button or a dedicated light button).

Održavanje

1. Čišćenje

Wipe the multimeter's case with a damp krpu i blagi deterdžent. Ne koristite abrazivna sredstva ili rastvarače. Prije čišćenja provjerite je li uređaj isključen i odvojen od bilo kojeg izvora napajanja.

2. Održavanje baterije

The built-in Lithium Ion battery should be charged regularly, especially if the device is not used for extended periods. The automatic shut-off feature helps prolong battery life. A low battery indicator will appear on the display when charging is required.
