4. Configuració

4.1 Instal·lació de la bateria

The multimeter is powered by batteries. To install or replace batteries:

1. Assegureu-vos que el multímetre estigui apagat i que els cables de prova estiguin desconnectats.
2. Localitzeu el compartiment de la bateria a la part posterior del dispositiu.
3. Unscrew the retaining screw(s) and remove the battery cover.
4. Insert new batteries, observing the correct polarity (+/-).
5. Torneu a col·locar la tapa de la bateria i fixeu-la amb el(s) cargol(s).

4.2 Connexió dels cables de prova

Always connect the black test lead to the 'COM' jack. Connect the red test lead to the appropriate jack based on the measurement type:

• Per al voltage, resistance, continuity, diode, temperature, and small current measurements (mA): Connect the red lead to the VΩmA jack.
• For high current measurements (up to 10A): Connect the red lead to the 10A jack.

5. Instruccions de funcionament

Before taking any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function.

5.1 Mesurar DC Voltage (V-)

1. Poseu el commutador rotatiu a la V- posició.
2. Connecteu el cable de prova vermell al costat positiu (+) del circuit i el cable de prova negre al costat negatiu (-).
3. Llegeix el voltage valor a la pantalla LCD.

5.2 Mesurar AC Voltage (V~)

1. Poseu el commutador rotatiu a la V~ posició.
2. Connecteu els cables de prova a través del voltatge de CAtage font.
3. Llegeix el voltage valor a la pantalla LCD.

5.3 Measuring Current (A-, A~)

CAUTION: To measure current, the multimeter must be connected in series with the circuit. Never connect it in parallel across a voltage source, as this can damage the multimeter and the circuit.

1. Determine if the current is DC (A-) or AC (A~).
2. Select the appropriate current range on the rotary switch (e.g., mA or 10A).
3. If measuring high current (above 200mA), move the red test lead to the 10A jack.
4. Talleu el circuit i connecteu el multímetre en sèrie.
5. Llegiu el valor actual a la pantalla LCD.

5.4 Mesura de la resistència (Ω)

1. Assegureu-vos que el circuit o component estigui desenergitzat abans de mesurar la resistència.
2. Poseu el commutador rotatiu a la Ω posició.
3. Connecteu els cables de prova al component que s'ha de mesurar.
4. Llegiu el valor de la resistència a la pantalla LCD.

5.5 Diode Test (→|→)

1. Poseu el commutador rotatiu a la Díode posició.
2. Connecteu el cable de prova vermell a l'ànode i el cable de prova negre al càtode del díode.
3. La pantalla mostrarà el volum d'avançtage drop. Reverse the leads; the display should show 'OL' (Open Loop) for a good diode.

5.6 Prova de continuïtat (♫)

1. Poseu el commutador rotatiu a la Continuïtat posició.
2. Connecteu els cables de prova a través del circuit o component.
3. If continuity exists (resistance below a certain threshold), the buzzer will sound.

5.7 Temperature Measurement (Temp)

1. Poseu el commutador rotatiu a la Temp posició.
2. Connect the temperature probe (if included and compatible) to the input jacks, observing polarity.
3. Col·loqueu la punta de la sonda sobre o a prop de l'objecte la temperatura del qual es vol mesurar.
4. Llegiu el valor de la temperatura a la pantalla LCD.

5.8 Transistor hFE Test (hFE)

1. Poseu el commutador rotatiu a la hFE posició.
2. Insert the transistor leads into the appropriate NPN or PNP sockets on the multimeter's hFE test socket.
3. Read the hFE (DC current gain) value on the LCD display.

6. Manteniment

6.1 Neteja

Netegeu el cas amb l'anunciamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the device is dry before use.

6.2 Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Remove batteries if the device will not be used for an extended period to prevent leakage.

6.3 Emmagatzematge

Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it out of reach of children.

7. Solució De Problemes

• Sense pantalla o pantalla tènue: Comproveu la instal·lació i la càrrega de la bateria. Canvieu les bateries si cal.
• Lectures incorrectes: Ensure test leads are properly connected to the correct input jacks. Verify the rotary switch is set to the appropriate function and range. Check for damaged test leads.
• Es mostra 'OL' (sobrecàrrega): The measured value exceeds the selected range. Switch to a higher range or ensure the circuit is within the multimeter's capabilities.
• No hi ha bip de continuïtat: Ensure the continuity function is selected and the circuit is de-energized. Check if the component has high resistance.
