2. Informació de seguretat

WARNING: Failure to follow these safety instructions can result in electric shock, fire, or personal injury.

• Always ensure the multimeter is in good working condition before use. Inspect test leads for damage.
• No apliqueu més del volum nominaltage (600V DC/AC) between the terminals or between any terminal and ground.
• Tingueu molta precaució quan treballeu amb voltagper sobre de 30 V CA RMS, 42 V pic o 60 V CC. Aquests voltagsuposen un risc de xoc.
• Desconnecteu sempre els cables de prova del circuit abans de canviar les funcions.

4. Configuració

4.1. Instal·lació de la bateria

The multimeter requires two 1.5V AAA batteries for operation. These are typically included and may be pre-installed. If not, or if replacement is needed:

1. Assegureu-vos que el multímetre estigui APAGAT.
2. Localitzeu la tapa del compartiment de la bateria a la part posterior de la unitat.
3. Feu servir un tornavís per treure el cargol que fixa la tapa.
4. Insert the two AAA batteries, observing the correct polarity (+ and - markings).
5. Substituïu la tapa del compartiment de la bateria i fixeu-la amb el cargol.

4.2. Connexió dels cables de prova

The test leads are essential for making measurements. Connect them as follows:

• Inseriu el cable de prova negre al connector 'COM' (comú).
• Per a la majoria de volumstage, resistance, and diode measurements, insert the red test lead into the 'VΩmA' jack.
• Per a mesures de corrent de fins a 10 A, inseriu el cable de prova vermell a la presa '10 A'.

5. Instruccions de funcionament

The multimeter features a rotary switch to select the desired measurement function and range. The display will show the measurement value.

5.1. Measuring DC Voltage (V---)

1. Connect the red test lead to the 'VΩmA' jack and the black test lead to the 'COM' jack.
2. Set the rotary switch to the desired DC Voltage range (e.g., 20V, 200V, 600V). If the voltage is unknown, start with the highest range and decrease as needed.
3. Connect the test leads in parallel across the component or circuit to be measured.
4. Llegeix el voltage valor a la pantalla.

5.2. Mesurar AC Voltage (V~)

1. Connect the red test lead to the 'VΩmA' jack and the black test lead to the 'COM' jack.
2. Set the rotary switch to the desired AC Voltage range (e.g., 200V, 600V).
3. Connect the test leads in parallel across the AC source or component.
4. Llegeix el voltage valor a la pantalla.

5.3. Measuring DC Current (A---)

CAUTION: To avoid damage to the multimeter or the circuit, never connect the multimeter in parallel when measuring current. Always connect it in series.

1. For currents up to 200mA, connect the red test lead to the 'VΩmA' jack. For currents up to 10A, connect the red test lead to the '10A' jack. The black test lead always connects to 'COM'.
2. Set the rotary switch to the desired DC Current range (e.g., 200µA, 2mA, 20mA, 200mA, 10A).
3. Open the circuit where current is to be measured and connect the multimeter in series.
4. Llegiu el valor actual a la pantalla.

5.4. Mesura de la resistència (Ω)

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

5.5. Prova de díodes

1. Connect the red test lead to the 'VΩmA' jack and the black test lead to the 'COM' jack.
2. Set the rotary switch to the diode symbol (→|).
3. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage gota.
4. Reverse the leads. The display should show 'OL' (Overload) for a good diode.

5.6. Prova de transistors hFE

1. Set the rotary switch to the 'hFE' position.
2. Insert the transistor hFE test adapter into the designated sockets on the multimeter.
3. Identify if the transistor is NPN or PNP and its Emitter (E), Base (B), Collector (C) terminals.
4. Insert the transistor leads into the corresponding holes on the hFE adapter.
5. Read the hFE (DC current gain) value on the display.

6. Manteniment

6.1. Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate measurements. Refer to Section 4.1 for battery installation instructions.

6.2. Neteja

Per netejar el multímetre, netegeu la carcassa amb aiguaamp drap i un detergent suau. No utilitzeu abrasius ni dissolvents. Assegureu-vos que el dispositiu estigui completament sec abans d'utilitzar-lo.

6.3. Emmagatzematge

If the multimeter is not used for an extended period, remove the batteries to prevent leakage and store the device in a cool, dry place away from direct sunlight.

7. Solució De Problemes

• No display or faint display: Check battery charge and ensure they are correctly installed. Replace batteries if necessary.
• 'OL' (Overload) on display: El valor mesurat supera l'interval seleccionat. Canvieu a un interval superior.
• Lectures incorrectes: Ensure test leads are properly connected, the correct function and range are selected, and the batteries are not low. Verify the circuit is de-energized for resistance measurements.
• No reading for current: Ensure the multimeter is connected in series with the circuit and the correct current jack (VΩmA or 10A) is used for the red lead.
