2. Bandymo laidų prijungimas

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.

Naudojimo instrukcijos

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

1. Maitinimo įjungimas/išjungimas

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 ttage, 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 ttage Matavimas

  1. Ensure the multimeter is powered on.
  2. Prijunkite bandymo laidus prie grandinės taškų, kuriuose yra įtampatage needs to be measured. The multimeter will automatically detect AC or DC voltage.
  3. Perskaitykite ttage reikšmė rodoma ekrane.

4. Atsparumo matavimas

  1. Svarbu: Prieš matuodami varžą, įsitikinkite, kad grandinė yra atjungta nuo įtampos.
  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. Nekontaktinis ttage (NCV) aptikimas

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. Tęstinumo testas

  1. Svarbu: Prieš atlikdami tęstinumo testą, įsitikinkite, kad grandinėje nėra įtampos.
  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. Duomenų sulaikymas

Norėdami sustabdyti dabartinį rodmenį ekrane, paspauskite mygtuką „HOLD“. Norėdami atšaukti laikymo funkciją, paspauskite jį dar kartą.

9. Žibintuvėlis ir foninis apšvietimas

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).

Priežiūra

1. Valymas

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. Akumuliatoriaus priežiūra

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.

3. Sandėliavimas

Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures. Disconnect test leads when storing.

Trikčių šalinimas

ProblemaGalima priežastisSprendimas
No display or device won't turn on.Išsikrovęs akumuliatorius arba įrenginys išjungtas.Charge the battery using the Type-C cable. Press and hold the power button to turn on.
Netikslūs rodmenys.Poor test lead connection, incorrect measurement technique, or exceeding input limits.Ensure test leads are firmly connected. Review operating instructions for correct measurement procedures. Do not exceed specified input ranges.
Multimeter automatically shuts off.Automatic power-off feature activated due to inactivity.This is normal behavior to conserve battery. Press the power button to turn it back on.
NCV detection not working or inconsistent.Distance to voltage source too far, or interference.Bring the NCV sensor closer to the suspected live wire. Ensure no other strong electromagnetic fields are present.
