Always adhere to basic safety precautions when using electrical testing equipment to prevent personal injury or damage to the meter or equipment under test.

• Netaikyti ttage arba srovė, viršijanti didžiausias skaitiklio nustatytas ribas.
• Dirbdami su įtampos srovėmis tekančiomis grandinėmis, būkite itin atsargūs.
• Ensure the test leads are in good condition, without any cracks or breaks in the insulation.
• Always turn off power to the circuit and discharge high-voltagPrieš matuodami varžą arba laidumą, išjunkite kondensatorius.
• Kad užtikrintumėte tikslius rodmenis, pakeiskite bateriją, kai pasirodys išsikrovusio akumuliatoriaus indikatorius.
• Nenaudokite skaitiklio, jei jis atrodo pažeistas arba jei korpusas yra atidarytas.

4.2 Bandymo laidų prijungimas

The multimeter comes with a pair of test leads (red and black).

• Įkiškite juodą bandymo laidą į „COM“ (bendrą) įvesties lizdą.
• Daugumai matavimų (tūriotage, resistance, continuity, and low current), insert the red test lead into the 'VΩmA' input jack.
• For high current measurements (up to 10A), insert the red test lead into the '10A MAX' input jack.

5. Naudojimo instrukcijos

To operate the multimeter, select the desired function using the rotary switch and connect the test leads to the circuit or component being measured.

5.1 DC tomastagMatavimas (V–)

Used for measuring direct current voltage in circuits.

1. Nustatykite sukamąjį jungiklį į norimą nuolatinės srovės įtampątage (V–) range (e.g., 200mV, 2V, 20V, 200V, 500V).
2. Prijunkite raudoną bandymo laidą prie teigiamos (+) grandinės pusės, o juodą bandymo laidą – prie neigiamos (-) pusės.
3. Perskaitykite ttage reikšmė ekrane.

5.2 AC ttage Matavimas (V∼)

Used for measuring alternating current voltage.

1. Nustatykite sukamąjį jungiklį į norimą kintamosios srovės garsumo lygį.tage (V∼) range (e.g., 200V, 500V).
2. Prijunkite bandymo laidus prie kintamosios srovės įtampostage šaltinis.
3. Perskaitykite ttage reikšmė ekrane.

5.3 Nuolatinės srovės matavimas (A–)

Used for measuring direct current flowing through a circuit.

1. Svarbu: Disconnect power to the circuit before connecting the multimeter in series.
2. Set the rotary switch to the desired DC Current (A–) range (e.g., 2000uA, 20mA, 200mA, 10A).
3. Insert the red test lead into the appropriate current input jack ('VΩmA' for low current, '10A MAX' for high current).
4. Prijunkite multimetrą nuosekliai prie grandinės, užtikrindami, kad per jį tekėtų srovė.
5. Įjunkite grandinę ir ekrane nuskaitykite srovės vertę.

5.4 Varžos matavimas (Ω)

Used for measuring the resistance of components.

1. Svarbu: Ensure the component is isolated from power and discharged before measuring resistance.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ, 20MΩ).
3. Prijunkite bandymo laidus prie komponento.
4. Perskaitykite pasipriešinimo vertę ekrane.

5.5 Tęstinumo testas

Used to check for an open or closed circuit.

1. Svarbu: Prieš atlikdami tęstinumo testą, įsitikinkite, kad grandinėje nėra įtampos.
2. Set the rotary switch to the continuity (♪) position.
3. Touch the test leads together; the meter should beep and display a low resistance value.
4. Connect the test leads across the circuit or component you wish to test.
5. If the circuit is continuous (closed), the meter will beep and display a low resistance. If it is open, no beep will sound, and the display will show 'OL' (Over Limit).

6. Priežiūra

6.1 Valymas

To maintain the accuracy and longevity of your multimeter, keep it clean.

• Nuvalykite dėklą su skelbimuamp šluoste ir švelniu plovikliu. Nenaudokite abrazyvinių medžiagų ar tirpiklių.
• Ensure no moisture enters the meter's casing.

6.2 Akumuliatoriaus keitimas

When the low battery indicator appears on the display, replace the 9V battery as described in Section 4.1. Failure to do so may result in inaccurate readings.

7. Problemų sprendimas

If your multimeter is not functioning as expected, consider the following common issues:

• Nėra ekrano arba ekranas silpnas: Patikrinkite bateriją. Jei reikia, pakeiskite.
• Neteisingi skaitymai: Ensure the correct function and range are selected. Verify test lead connections. Check battery level.
• 'OL' (Over Limit) Display: The measured value exceeds the selected range. Switch to a higher range or ensure the circuit is closed for continuity tests.
• Nėra tęstinumo pyptelėjimo: Ensure the circuit is de-energized. Check if the component is truly open.

Jei problemos išlieka, susisiekite su klientų aptarnavimo tarnyba.
