4. Configuració

4.1 Instal·lació de la bateria

The Voltcraft VC-11 requires a 9V battery for operation (not included). To install or replace the battery:

1. Assegureu-vos que el multímetre estigui apagat i desconnecteu tots els cables de prova.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior del mesurador.
3. Feu servir un tornavís per treure el cargol que fixa la tapa de la bateria.
4. Traieu la coberta amb cura.
5. Connect a new 9V battery to the battery clip, observing correct polarity.
6. Col·loqueu la bateria al compartiment i torneu a col·locar la tapa, fixant-la amb el cargol.

4.2 Connexió dels cables de prova

Always connect the black test lead to the 'COM' (common) jack. Connect the red test lead to the appropriate input jack based on the desired measurement:

• Per al voltage (V), Resistance (Ω), Diode, and Continuity measurements, connect the red lead to the 'VΩmA' jack.
• For Current (A) measurements, connect the red lead to the 'VΩmA' jack (for mA range).

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 and range.

5.1 Mesurar DC Voltage (V=)

1. Ajusteu l'interruptor rotatiu al volum de CC desitjattage (V=) range (e.g., 200mV, 2V, 20V, 200V, 250V). If the voltage is unknown, start with the highest range and decrease as needed.
2. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
3. Connecteu les sondes de prova en paral·lel al component o circuit que s'ha de mesurar.
4. Llegeix el voltage valor a la pantalla LCD.

5.2 Mesurar AC Voltage (V~)

1. Ajusteu l'interruptor rotatiu al volum de CA desitjattage (V~) range (e.g., 200V, 250V).
2. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
3. Connect the test probes in parallel across the AC source or component.
4. Llegeix el voltage valor a la pantalla LCD.

5.3 Measuring DC Current (A=)

1. Set the rotary switch to the desired DC Current (A=) range (e.g., 2000µA, 20mA, 200mA).
2. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
3. ADVERTIMENT: To measure current, the meter must be connected in series with the circuit. Break the circuit and insert the meter.
4. Connect the test probes in series with the circuit.
5. Llegiu el valor actual a la pantalla LCD.

5.4 Mesura de la resistència (Ω)

1. Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2000kΩ).
3. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
4. Connecteu les sondes de prova al component que s'ha de mesurar.
5. Llegiu el valor de la resistència a la pantalla LCD.

5.5 Prova de díodes

1. Assegureu-vos que el circuit estigui desenergitzat.
2. Set the rotary switch to the Diode symbol (usually next to resistance).
3. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
4. Connecteu la sonda vermella a l'ànode i la sonda negra al càtode del díode. La pantalla mostrarà el volum directe.tage gota.
5. Reverse the probes. The display should show 'OL' (Overload) for a good diode.

5.6 Prova de continuïtat

1. Assegureu-vos que el circuit estigui desenergitzat.
2. Set the rotary switch to the Continuity symbol (usually next to diode/resistance).
3. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
4. Connecteu les sondes de prova a través del circuit o component.
5. If the resistance is below a certain threshold (typically 30-50Ω), the meter will emit an audible beep, indicating continuity.

6. Manteniment

6.1 Neteja

Netegeu el comptador amb anuncisamp drap i un detergent suau. No utilitzeu abrasius ni dissolvents. Assegureu-vos que el mesurador estigui completament sec abans d'utilitzar-lo.

6.2 Substitució de la bateria

When the battery symbol appears on the LCD display, the 9V battery needs to be replaced. Refer to section 4.1 for battery installation instructions.
