4. Konfigurazioa

4.1 Bateriaren instalazioa

1. Kokatu bateriaren konpartimendua multimetroaren atzealdean.
2. Erabili bihurkin txiki bat bateriaren estalkia irekitzeko.
3. Insert the provided 12V battery, observing the correct polarity (+ and -).
4. Jarri bateriaren estalkia eta lotu torlojuarekin.

4.2 Proba-kableak konektatzea

The multimeter comes with a set of test leads. Connect them as follows:

• Sartu beltza test lead into the COM (common) jack.
• Sartu gorria test lead into the VΩmA jack for most measurements (Voltage, Resistance, Current).

5. Funtzionamendu-argibideak

Before taking any measurements, ensure the meter is set to the correct function and range. If the value is unknown, start with the highest range and work downwards.

5.1 Piztea/Itzaltzea eta Funtzioen Hautaketa

• To turn on the meter, rotate the central dial from the 'OFF' position to the desired measurement function.
• To turn off the meter, rotate the central dial back to the 'OFF' position.

5.4 DC Current Measurement (mA=)

Kontuz: Never connect the meter in parallel for current measurement. Always connect in series with the circuit.

1. Set the rotary dial to the 200mA DC Current range.
2. Break the circuit and connect the meter in series, ensuring the current flows through the meter.
3. Irakurri uneko balioa pantailan.

5.5 Erresistentziaren neurketa (Ω)

1. Ensure the circuit or component is indargabetuta before measuring resistance.
2. Set the rotary dial to the desired Resistance range (2KΩ, 20KΩ, 200KΩ, or 2MΩ).
3. Konektatu proba-kableak neurtu beharreko osagaira.
4. Irakurri erresistentziaren balioa pantailan.

5.6 Diodoen proba (→|)

1. Set the rotary dial to the Diode Test function.
2. Konektatu proba-kable gorria diodoaren anodora eta proba-kable beltza katodora.
3. Pantailak aurrerako bolumena erakutsiko dutage drop. Reverse the leads; an open circuit (OL) reading indicates a good diode.

5.7 Jarraitutasun-proba ())))

1. Set the rotary dial to the Continuity Test function.
2. Konektatu proba-kableak zirkuituan edo osagaian zehar.
3. An audible beep indicates continuity (low resistance). The display will show the resistance value.

6. Mantentzea

6.1 Bateria ordezkatzea

When the battery symbol appears on the display, the 12V battery needs to be replaced. Follow the steps in Section 4.1.

6.2 Garbiketa

Garbitu neurgailuaren kaxa iragarkiarekinamp oihal eta detergente leun batekin. Ez erabili urratzailerik edo disolbatzailerik. Ziurtatu neurgailua lehor dagoela erabili aurretik.

6.3 Biltegiratzea

If the meter is not used for an extended period, remove the battery to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Arazoak

• Ez dago pantailarik edo pantaila ahula: Egiaztatu bateria. Ordeztu behar izanez gero.
• Irakurketa okerrak:
  • Ensure the test leads are properly connected to the correct jacks.
  • Verify the rotary dial is set to the correct function and range.
