4.2. Connexió dels cables de prova

Connecteu sempre el cable de prova negre al COM jack. Connect the red test lead to the appropriate jack based on the measurement type:

• Per al voltage, Resistance, Diode, Continuity, and small Current (up to 200mA): Connect the red lead to the VΩmA jack.
• For large DC Current (up to 10A): Connect the red lead to the 10 ADC jack.

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. Mesura de la tensió de CCtage (V=)

1. Connecteu el cable de prova vermell al VΩmA jack and the black test lead to the COM jack.
2. Ajusteu l'interruptor rotatiu al volum de CC desitjattage range (e.g., 20V, 200V, 600V). Start with the highest range if the voltage es desconeguda.
3. Connecteu les sondes de prova al component o circuit que s'ha de mesurar, observant la polaritat.
4. Llegeix el voltage valor a la pantalla LCD.

5.2. Mesurar AC Voltage (V~)

1. Connecteu el cable de prova vermell al VΩmA jack and the black test lead to the COM jack.
2. Ajusteu l'interruptor rotatiu al volum de CA desitjattagrang electrònic (per exemple, 200 V, 600 V). Comenceu amb el rang més alt si el volumtage es desconeguda.
3. Connect the test probes across the AC source or component.
4. Llegeix el voltage valor a la pantalla LCD.

5.3. Mesura del corrent continu (A=)

Precaució: Never connect the meter in parallel with a voltage source when measuring current. This can blow the fuse or damage the meter.

1. Determine the expected current. For currents up to 200mA, connect the red lead to VΩmA. For currents up to 10A, connect the red lead to 10 ADC. Connect the black lead to COM.
2. Set the rotary switch to the appropriate DC Current range (e.g., 2mA, 20mA, 200mA, 10A).
3. De-energize the circuit and open it at the point where current is to be measured.
4. Connect the meter in series with the circuit.
5. Re-energize the circuit and read the current value on the LCD display.

5.4. Mesura de la resistència (Ω)

4. Reverse the probes. The display should show "OL" (Open Loop) for a good diode.

5.6. Prova de continuïtat

1. Connecteu el cable de prova vermell al VΩmA jack and the black test lead to the COM jack.
2. Set the rotary switch to the Continuity symbol ()))).
3. Connecteu les sondes de prova a través del circuit o component.
4. If the resistance is below approximately 50Ω, the buzzer will sound, indicating continuity. The display will also show the resistance value.

5.7. hFE (Transistor) Test

1. Poseu el commutador rotatiu a la hFE posició.
2. Identify if the transistor is NPN or PNP.
3. Insert the transistor leads (Emitter, Base, Collector) into the corresponding holes in the hFE socket.
4. Read the hFE value (DC current gain) on the LCD display.
