3. Configuració
3.1. Instal·lació de la bateria
- Ensure the multimeter is turned OFF and all test leads are disconnected.
- Localitzeu la tapa del compartiment de la bateria a la part posterior del mesurador (vegeu la figura 1).
- Descargoleu el(s) cargol(s) de subjecció i retireu la coberta amb cura.
- Insert a new 9V battery (NEDA 1604 or 6F22 type), observing the correct polarity (+ and -).
- Torneu a col·locar la tapa del compartiment de la bateria i fixeu-la amb el(s) cargol(s).
3.2. Connexió dels cables de prova
- Connecteu el vermell test lead to the "VΩmA" input jack.
- Connecteu el negre test lead to the "COM" (common) input jack.
- For current measurements exceeding 200mA (up to 10A), connect the red test lead to the "10A" input jack.
4. Instruccions de funcionament
4.1. Selecció de la funció
Turn the rotary switch to the desired measurement function and range. Always start with a higher range if the approximate value is unknown to prevent overloading the meter.
4.2. Mesura de la tensió de CCtage (V–)
- Ajusteu l'interruptor rotatiu al volum de CC desitjattage (V–) range (e.g., 20V, 200V).
- Connecteu el cable de prova vermell al costat positiu (+) del circuit i el cable de prova negre al costat negatiu (-).
- Llegeix el voltage valor a la pantalla LCD.
4.3. Mesurar AC Voltage (V∼)
- Ajusteu l'interruptor rotatiu al volum de CA desitjattage (V∼) range (e.g., 200V, 750V).
- Connecteu els cables de prova a través del voltatge de CAtage font.
- Llegeix el voltage valor a la pantalla LCD.
4.4. Measuring DC Current (A–)
Precaució: To measure current, the meter must be connected in series with the circuit. Never connect the meter in parallel with a voltagla font quan està en mode de corrent, ja que això pot danyar el mesurador i el circuit.
- Set the rotary switch to the desired DC Current (A–) range (e.g., 20mA, 200mA, 10A).
- For currents up to 200mA, ensure the red lead is in the "VΩmA" jack. For currents up to 10A, move the red lead to the "10A" jack.
- Obriu el circuit on es vol mesurar el corrent i connecteu el mesurador en sèrie.
- Llegiu el valor actual a la pantalla LCD.
4.5. Measuring Resistance (Ω)
Precaució: Ensure the circuit or component under test is de-energized before measuring resistance.
- Set the rotary switch to the desired Resistance (Ω) range (e.g., 200Ω, 2kΩ, 200kΩ).
- Connecteu els cables de prova al component o circuit que s'ha de mesurar.
- Llegiu el valor de la resistència a la pantalla LCD.
4.6. Diode Test (→|–)
- Set the rotary switch to the Diode Test (→|–) position.
- Connect the red test lead to the anode of the diode and the black test lead to the cathode.
- La pantalla mostrarà el volum d'avançtage drop (typically 0.5V to 0.8V for silicon diodes).
- Inverteix els cables. La pantalla hauria de mostrar "OL" (bucle obert) per a un díode en bon estat.
4.7. Transistor (hFE) Test
- Col·loqueu l'interruptor giratori a la posició hFE.
- Identify if the transistor is NPN or PNP.
- Insert the transistor's emitter, base, and collector leads into the corresponding sockets on the hFE test socket.
- Read the hFE (DC current gain) value on the display.
5. Manteniment
5.1. Substitució de la bateria
When the low battery indicator appears on the display, replace the 9V battery as described in Section 3.1. Using a low battery can lead to inaccurate readings.
5.2. Substitució de fusibles
If the current measurement function stops working, the fuse may need replacement. This operation should only be performed by qualified personnel.
- Ensure the multimeter is turned OFF and all test leads are disconnected.
- Open the back casing of the meter (this may involve more screws than just the battery compartment).
- Locate the blown fuse and replace it with a fuse of the exact same type and rating (e.g., F200mA/250V for mA range, F10A/250V for 10A range). Refer to the internal markings or specifications for precise fuse ratings.
- Carefully reassemble the meter, ensuring all screws are tightened.
5.3. Neteja
Netegeu el comptador amb anuncisamp cloth and mild detergent. Do not use abrasives or solvents. Keep the meter dry.
