Informació de seguretat

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

• No supereu els valors d'entrada màxims especificats per a cada funció.
• Assegureu-vos que els cables de prova estiguin en bon estat i connectats correctament abans de fer mesures.
• Tingueu precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC, ja que representen un perill de descàrrega elèctrica.
• No feu servir el multímetre si sembla que està danyat o si la carcassa està oberta.
• Always disconnect power to the circuit under test before measuring resistance or continuity.
• Utilitzeu el volum sense contactetage (NCV) function as an initial check, but always verify with direct contact measurements when safety is critical.

Contingut del paquet

Verifiqueu que tots els elements siguin presents al paquet:

• NJTY T3 Multimeter (1 unit)
• Test Leads (1 pair, red and black)

Configuració

1. Càrrega inicial

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. Connect the Type-C end of the charging cable to the multimeter's charging port.
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. Connexió dels cables de prova

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.

Instruccions de funcionament

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

1. Encendre/apagar

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 Mesura

1. Assegureu-vos que el multímetre estigui engegat.
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. Llegeix el voltagel valor que es mostra a la pantalla.

4. Mesura de Resistències

1. Important: Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
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. Vol sense contactetage (NCV) Detecció

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

Aquesta funció ajuda a identificar els cables actius en un circuit de CA.

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. Prova de continuïtat

1. Important: Assegureu-vos que el circuit estigui desenergitzat abans de realitzar una prova de continuïtat.
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. Retenció de dades

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function.

9. Llanterna i retroiluminació

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).

Manteniment

1. Neteja

Wipe the multimeter's case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is off and disconnected from any power source before cleaning.

2. Cura de la bateria

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.
