5. Funtzionamendu-argibideak

Before operation, ensure the test leads are properly connected and the function dial is set to the desired measurement mode.

5.1. AC/DC Voltage Measurement (V~) / (V=)

1. Biratu biraketa-etengailua "V~" posiziora (AC Boltage) edo "V=" (DC bolumenatage) posizioa.
2. Connect the red test lead to the "V" input jack and the black test lead to the "COM" input jack.
3. Ukitu proba-zundak zirkuituko puntuetan, non bolumena dagoen.tage neurtu behar da.
4. Irakurri liburukiatage value on the display. The unit will automatically select the appropriate range.

5.2. AC/DC Current Measurement (mA~) / (mA=)

1. Turn the rotary switch to the "mA~" (AC Current) or "mA=" (DC Current) position.
2. Connect the red test lead to the "mA" input jack and the black test lead to the "COM" input jack.
3. Kontuz: To measure current, the multimeter must be connected in series with the circuit. Ensure the circuit is de-energized before connecting the multimeter.
4. Break the circuit and insert the multimeter in series.
5. Berriro piztu zirkuitua eta irakurri uneko balioa pantailan.

5.3. Erresistentziaren neurketa (Ω)

1. Biratu biraketa-etengailua "Ω" (Erresistentzia) posiziora.
2. Connect the red test lead to the "V" input jack and the black test lead to the "COM" input jack.
3. Ziurtatu neurtu beharreko zirkuitua edo osagaia desenergizatuta dagoela.
4. Touch the test probes across the component.
5. Irakurri erresistentziaren balioa pantailan.

5.4. Logic Level Test

This function allows for quick testing of digital logic levels.

1. Turn the rotary switch to the "LOGIC" position.
2. Connect the black test lead to the "COM" input jack. The red test lead is integrated into the pen tip.
3. Touch the pen tip to the point on the circuit where the logic level is to be tested.
4. The display will indicate:
   • Maila altua: voltage is >3.5V
   • Maila baxua: voltage <3.5V da

5.5. Diode Check (→|)

1. Turn the rotary switch to the "→|" (Diode) position.
2. Connect the red test lead to the "V" input jack and the black test lead to the "COM" input jack.
3. Konektatu zunda gorria diodoaren anodoari eta zunda beltza katodoari.
4. Irakurri aurrerako liburukiatage drop on the display. Reverse the probes to check for open circuit (OL) indication.

5.6. Continuity Test (•)))

1. Turn the rotary switch to the "•)))" (Continuity) position.
2. Connect the red test lead to the "V" input jack and the black test lead to the "COM" input jack.
3. Touch the test probes to the two points of the circuit or component to be tested.
4. If continuity exists (resistance below a certain threshold), the multimeter will emit an audible beep and display a low resistance value. An "OL" (Open Loop) indicates no continuity.

5.7. Datuen atxikipena (HOLD)

Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.

5.8. Maximum Value Hold (MAX H)

Press the "MAX H" button to activate the maximum value hold function. The multimeter will continuously monitor and display the highest value measured since the function was activated. Press it again to exit this mode.

5.9. Itzalketa automatikoa

To conserve battery life, the MS8211D is equipped with an auto power-off feature. If no operation is performed for approximately 15 minutes, the multimeter will automatically shut down. To reactivate, turn the rotary switch to the "OFF" position and then back to the desired measurement function.

6. Mantentzea

• Garbiketa: Wipe the multimeter's casiniragarkiarekin gamp oihala eta detergente leuna. Ez erabili urratzaileak edo disolbatzaileak.
• Biltegiratzea: Gorde gailua leku fresko eta lehor batean, eguzki-argitik eta muturreko tenperaturetatik babestuta. Denbora luzez gordetzen baduzu, kendu bateriak isuriak saihesteko.
• Kalibrazioa: For professional use, periodic calibration by qualified personnel is recommended to ensure accuracy.
• Bateria ordezkatzea: Replace batteries promptly when the low battery indicator appears on the display to ensure accurate readings and proper operation.
