Informații de siguranță

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

  • Nu depășiți valorile maxime de intrare specificate pentru fiecare funcție.
  • Asigurați-vă că sondele de testare sunt în stare bună și conectate corect înainte de a efectua măsurători.
  • Aveți grijă când lucrați cu voltagpeste 30V AC RMS, 42V peak sau 60V DC, deoarece acestea prezintă un pericol de electrocutare.
  • Nu utilizați multimetrul dacă pare deteriorat sau dacă carcasa este deschisă.
  • Always disconnect power to the circuit under test before measuring resistance or continuity.
  • Folosește Volumul fără Contacttage (NCV) function as an initial check, but always verify with direct contact measurements when safety is critical.

Înființat

1. Încărcarea inițială

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. Conectați capătul de tip C al cablului de încărcare la portul de încărcare al multimetrului.
  2. Conectați capătul USB-A al cablului de încărcare la un adaptor de alimentare USB standard (nu este inclus) sau la portul USB al unui computer.
  3. The charging indicator on the multimeter will illuminate during charging and turn off when fully charged.

2. Conectarea cablurilor de testare

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.

Instrucțiuni de operare

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

1. Pornire/Oprire

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 Măsurare

  1. Ensure the multimeter is powered on.
  2. Conectați sondele de testare la punctele circuitului unde voltage needs to be measured. The multimeter will automatically detect AC or DC voltage.
  3. Citiți voltagvaloarea afișată pe ecran.

4. Măsurarea rezistenței

  1. Important: Asigurați-vă că circuitul este dezactivat înainte de a măsura rezistența.
  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. fără contacttage (NCV) Detectie

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 de continuitate

  1. Important: Asigurați-vă că circuitul este dezactivat înainte de a efectua un test de continuitate.
  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. Reținerea datelor

Apăsați butonul „HOLD” pentru a îngheța valoarea curentă de pe afișaj. Apăsați-l din nou pentru a dezactiva funcția de menținere a valorii.

9. Lanternă și iluminare de fundal

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).

Întreţinere

1. Curatenie

Wipe the multimeter's case with a damp o lavetă și un detergent blând. Nu utilizați abrazivi sau solvenți. Asigurați-vă că dispozitivul este oprit și deconectat de la orice sursă de alimentare înainte de curățare.

2. Îngrijirea bateriei

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.
