5. Configuració

5.1. Instal·lació de la bateria

1. Assegureu-vos que el multímetre estigui APAGAT.
2. Localitzeu el compartiment de la bateria a la part posterior del mesurador.
3. Utilitzeu un tornavís per obrir la tapa de la bateria.
4. Introduïu la pila de 9 V, respectant la polaritat correcta (+/-).
5. Substituïu la tapa de la bateria i fixeu-la amb el cargol.

5.2. Connexió dels cables de prova

• Inseriu el cable de prova negre al connector "COM" (comú).
• Per a la majoria de volumstage, resistance, and continuity measurements, insert the red test lead into the "VΩHz" jack.
• For current measurements up to 400mA, insert the red test lead into the "µAmA" jack.
• For current measurements up to 20A, insert the red test lead into the "20A" jack.

6. Instruccions de funcionament

6.1. Turning On/Off and Function Selection

Rotate the central rotary switch to the desired measurement function to turn the meter ON. Turn the switch to "OFF" to power down the meter.

6.2. AC/DC Voltage Mesura

1. Connect the black lead to COM and the red lead to VΩHz.
2. Rotate the switch to the "V~" (AC Voltage) o "V-" (Volumen de CCtage) posició.
3. The meter will automatically select the range. For manual ranging, press the GAMMA botó.
4. Toqueu les sondes de prova als punts del circuit on el volumtage s'ha de mesurar.

6.3. Mesura de corrent AC/DC

1. IMPORTANT: Desconnecteu l'alimentació del circuit abans de connectar el mesurador en sèrie.
2. Connect the black lead to COM. Connect the red lead to "µAmA" for small currents or "20A" for larger currents.
3. Rotate the switch to the "A~" (AC Current) or "A-" (DC Current) position.
4. Talleu el circuit i connecteu el comptador en sèrie amb la càrrega.
5. Apply power to the circuit and read the current.

6.4. Mesura de Resistències

1. Connect the black lead to COM and the red lead to VΩHz.
2. Rotate the switch to the "Ω" (Resistance) position.
3. Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
4. Touch the probes across the component to measure its resistance.

6.5. Vol sense contactetage (NCV) Detecció

1. Rotate the switch to the "NCV" position.
2. Move the top tip of the meter near the conductor or outlet.
3. The meter will emit an audible beep and the NCV indicator will light up if AC voltages detecta e.

6.6. Other Functions (Diode, Continuity, hFE, Capacitance, Frequency)

Refer to the specific symbols on the rotary switch and the detailed specifications table for instructions on using Diode Check, Continuity, hFE, Capacitance, and Frequency/Duty Cycle measurements. Use the multi-function adapter for hFE and capacitance tests as needed.

7. Manteniment

7.1. Atenció general

• Keep the meter dry. If it gets wet, wipe it dry immediately.
• Use and store the meter in normal temperature environments. Extreme temperatures can shorten the life of electronic devices.
• Handle the meter gently and carefully. Dropping it can damage circuit boards and cases.
• Keep the meter away from dust and dirt, which can cause premature wear of parts.
• Netegeu el comptador amb anuncisamp drap de tant en tant per mantenir-lo nou. No utilitzeu productes químics aggressivs, dissolvents de neteja o detergents forts.

7.2. Substitució de la bateria

When the battery symbol appears on the display, replace the 9V battery as described in the Setup section (5.1). Always remove batteries if the meter is not going to be used for an extended period.

8. Solució De Problemes

8.1. Display Shows "OL" (Overload)

If the display shows "OL" during a measurement, it indicates that the input value exceeds the selected range or the maximum measurement capability of the meter. Try selecting a higher range if available, or ensure the measured value is within the meter's specifications.

8.2. No Reading or Incorrect Reading

• Comproveu el nivell de la bateria i substituïu-la si és baixa.
• Ensure test leads are securely connected to the correct jacks.
• Verify the rotary switch is set to the appropriate function and range for the measurement.
• Inspect test leads for damage or breaks.
• Ensure proper contact between probes and the circuit under test.
