• Always insert the negre cable de prova a la COM Jack (comú).
• Per a la majoria de mesures (voltage, resistance, diode, continuity, low current), insert the vermell cable de prova a la VΩmA jack.
• For high current measurements (e.g., 10A), insert the vermell test lead into the dedicated 10A jack (if present on your model).

5. Instruccions de funcionament

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

5.1 Mesurar DC Voltage (V—)

1. Connect the red lead to the VΩmA jack and the black lead to the COM jack.
2. Ajusteu l'interruptor rotatiu al volum de CC desitjattage (V—) range. Start with the highest range if the voltage es desconeguda.
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. Connect the red lead to the VΩmA jack and the black lead to the COM jack.
2. Ajusteu l'interruptor rotatiu al volum de CA desitjattage (V∼) range. Start with the highest range if the voltage es desconeguda.
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.

5.3 Measuring DC Current (A—)

CAUTION: Never connect the multimeter in series with a voltage source when set to current measurement, as this can blow the fuse or damage the meter.

1. Apagueu el circuit.
2. For low current, connect the red lead to the VΩmA jack. For high current (if applicable), connect the red lead to the 10A jack. Connect the black lead to the COM jack.
3. Set the rotary switch to the desired DC Current (A—) range. Start with the highest range.
4. Break the circuit and connect the multimeter in series with the circuit.
5. Resta l'alimentació del circuit.
6. Llegiu el valor actual a la pantalla LCD.
7. Turn off power before disconnecting the multimeter.

5.4 Mesura de la resistència (Ω)

1. Connect the red lead to the VΩmA jack and the black lead to the COM jack.
2. Set the rotary switch to the desired Resistance (Ω) range.
3. Ensure the component under test is de-energized and isolated from the circuit.
4. Connecteu les sondes de prova a través del component.
5. Llegiu el valor de la resistència a la pantalla LCD.

5.5 Prova de díodes

1. Connect the red lead to the VΩmA jack and the black lead to the COM jack.
2. Set the rotary switch to the Diode symbol (→|).
3. Connect the red probe to the anode and the black probe to the cathode of the diode. The display should show a forward voltage drop (e.g., 0.5V to 0.7V for silicon diodes).
4. Reverse the probes. The display should show "OL" (Open Loop) for a good diode.

5.6 Prova de continuïtat

1. Connect the red lead to the VΩmA jack and the black lead to the COM jack.
2. Posicioneu el commutador rotatiu al símbol de continuïtat (♫).
3. Connecteu les sondes de prova a través del circuit o component.
4. If continuity exists (low resistance), the multimeter will emit an audible beep. The display will show the resistance value.

5.7 Prova de transistors (hFE)

1. Col·loqueu l'interruptor giratori a la posició hFE.
2. Identify the type of transistor (NPN or PNP) and its emitter, base, and collector leads.
3. Insert the transistor leads into the corresponding holes in the hFE socket.
4. Read the hFE (DC current gain) value on the LCD display.
