5. Instruccions de funcionament

Turn the rotary switch to the desired function. The meter typically defaults to auto-ranging. Press the 'SEL' button to switch between functions within a single rotary switch position (e.g., AC/DC voltage, díode/continuïtat).

5.1 DC/AC Voltage Measurement (V, mV)

1. Connect the black lead to COM and the red lead to VΩHz.
2. Turn the rotary switch to the V (Voltage) position. The meter will typically default to DCV. Press 'SEL' to switch to ACV if needed.
3. Connecteu les sondes de prova en paral·lel al circuit o component que s'està provant.
4. Llegeix el voltage valor a la pantalla.

5.2 DC/AC Current Measurement (A, mA, uA)

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

1. Connect the black lead to COM. Connect the red lead to mA for currents up to 600mA, or to A for currents up to 10A.
2. Turn the rotary switch to the A (Current) position. Press 'SEL' to switch between DC/AC current or different ranges (uA, mA, A) if necessary.
3. Open the circuit where current is to be measured and connect the meter in series.
4. Llegiu el valor actual a la pantalla.

5.3 Mesura de resistència (Ω)

1. Connect the black lead to COM and the red lead to VΩHz.
2. Turn the rotary switch to the Ω (Resistance) position.
3. Ensure the circuit is de-energized before measuring resistance. Connect the test probes across the component.
4. Llegiu el valor de resistència a la pantalla.

5.4 Capacitance Measurement (nF, uF, mF)

1. Connect the black lead to COM and the red lead to VΩHz.
2. Turn the rotary switch to the Capacitance position.
3. Discharge the capacitor completely before measurement. Connect the test probes across the capacitor terminals.
4. Llegiu el valor de la capacitat a la pantalla.

5.5 Frequency Measurement (Hz, KHz, MHz)

1. Connect the black lead to COM and the red lead to VΩHz.
2. Turn the rotary switch to the Hz (Frequency) position.
3. Connecteu les sondes de prova en paral·lel a la font de senyal.
4. Llegiu el valor de la freqüència a la pantalla.

5.6 Prova de díodes

1. Connect the black lead to COM and the red lead to VΩHz.
2. Turn the rotary switch to the Diode/Continuity position. Press 'SEL' until the diode symbol appears.
3. Connect the red probe to the anode and the black probe to the cathode of the diode.
4. A forward voltage drop will be displayed for a good diode. Reverse the probes; the display should show 'OL' (open loop).

5.7 Prova de continuïtat

1. Connect the black lead to COM and the red lead to VΩHz.
2. Turn the rotary switch to the Diode/Continuity position. Press 'SEL' until the continuity symbol appears.
3. Connecteu les sondes de prova a través del circuit o component.
4. If continuity exists (resistance below approximately 50Ω), the buzzer will sound.

5.8 Mesura de la temperatura

1. Connect the temperature probe (K-type thermocouple) to the VΩHz and COM jacks, observing polarity.
2. Turn the rotary switch to the Temp position.
3. Col·loqueu la punta de la sonda sobre o a prop de l'objecte la temperatura del qual es vol mesurar.
4. Read the temperature value on the display (in °C or °F).

5.9 Vol. sense contactetage (NCV) Detecció

1. Gireu l'interruptor giratori a la posició NCV.
2. Move the top end of the meter close to the conductor being tested.
3. Si AC voltage is detected, the meter will emit an audible beep and the NCV indicator will light up.

6. Manteniment

6.1 Neteja

Netegeu el cas amb l'anunciamp drap i detergent suau. No utilitzeu abrasius ni dissolvents. Mantingueu els terminals d'entrada lliures de brutícia i humitat.

6.2 Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Using the meter with a low battery can lead to inaccurate readings.

6.3 Canvi de fusibles

If the current measurement function fails, the fuse may need replacement. The AN8009 typically uses two fuses: a 200mA/250V fast-blow fuse for the mA input and a 10A/250V fast-blow fuse for the A input. Refer to the markings on the meter for exact fuse specifications. Fuse replacement should only be performed by qualified personnel.

1. Ensure the meter is powered off and test leads are disconnected.
2. Open the battery compartment and then the main casing screws (if applicable, consult the meter's physical design).
3. Carefully remove the old fuse and replace it with a new fuse of the identical type and rating.
4. Reassemble the meter, ensuring all screws are tightened.

6.4 Emmagatzematge

Si no heu d'utilitzar el mesurador durant un període prolongat, traieu-ne les piles per evitar fuites i danys. Guardeu el mesurador en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.

7. Solució De Problemes

• No display or faint display: Comproveu la instal·lació i la càrrega de la bateria. Canvieu les bateries si cal.
• Es mostra 'OL' (sobrecàrrega): The input value exceeds the selected range or the maximum measurement capability of the meter. Select a higher range or ensure the input is within specifications.
• Lectures incorrectes: Check battery level, ensure test leads are properly connected, and verify the correct function is selected. Clean input jacks if dirty.
• La mesura de corrent no funciona: Check the fuse for the respective current input (mA or A). Replace if blown.
