4. Configuració

4.1 Instal·lació de la bateria

The Ingco DM2002 requires alkaline batteries for operation. Ensure the correct polarity when inserting batteries.

1. Localitzeu el compartiment de la bateria a la part posterior del multímetre.
2. Feu servir un tornavís per obrir la tapa del compartiment de la bateria.
3. Insert the required alkaline batteries, observing the polarity markings (+ and -).
4. Substituïu la tapa del compartiment de la bateria i fixeu-la amb el cargol.

4.2 Connexió dels cables de prova

La connexió correcta dels cables de prova és essencial per a mesures precises i segures.

• Insert the black test lead into the 'COM' (Common) input jack.
• Per a la majoria de mesures (voltage, resistance, capacitance, frequency, temperature, and small currents), insert the red test lead into the 'VΩmA' input jack.
• For measuring large currents (up to 10A), insert the red test lead into the '10A' input jack. Ensure the function switch is set to the appropriate current range.

5. Instruccions de funcionament

Before taking any measurement, ensure the test leads are correctly connected and the function switch is set to the desired measurement mode.

5.1 Mesurar AC/DC Voltage (V~ / V-)

1. Connect the black test lead to 'COM' and the red test lead to 'VΩmA'.
2. Set the function switch to the desired AC Voltage (V~) o Volum de corrent continutage (V-) range.
3. Connecteu les sondes de prova en paral·lel al component o circuit que s'ha de mesurar.
4. Llegeix el voltage valor a la pantalla LCD.

5.2 Measuring AC/DC Current (A~ / A-)

Precaució: No connecteu mai el multímetre en paral·lel amb un voltímetre.tage source when measuring current, as this can damage the meter and pose a safety risk.

1. Connect the black test lead to 'COM'.
2. For currents up to 200mA, connect the red test lead to 'VΩmA'. For currents up to 10A, connect the red test lead to '10A'.
3. Set the function switch to the desired AC Current (A~) or DC Current (A-) range.
4. Open the circuit where the current is to be measured and connect the multimeter in series with the circuit.
5. Llegiu el valor actual a la pantalla LCD.

5.3 Mesura de la resistència (Ω)

1. Assegureu-vos que el circuit estigui desenergitzat abans de mesurar la resistència.
2. Connect the black test lead to 'COM' and the red test lead to 'VΩmA'.
3. Set the function switch to the desired Resistance (Ω) range.
4. Connecteu les sondes de prova al component que s'ha de mesurar.
5. Llegiu el valor de la resistència a la pantalla LCD.

5.4 Measuring Capacitance (F)

1. Assegureu-vos que el condensador estigui completament descarregat abans de mesurar per evitar danys al mesurador.
2. Connect the black test lead to 'COM' and the red test lead to 'VΩmA'.
3. Set the function switch to the Capacitance (F) range.
4. Connecteu les sondes de prova als terminals del condensador.
5. Llegiu el valor de la capacitat a la pantalla LCD.

5.5 Measuring Frequency (Hz) and Temperature (°C/°F)

Refer to the specific markings on the rotary switch for Frequency (Hz) and Temperature (°C/°F) functions. The connection method for these measurements typically involves the 'COM' and 'VΩmA' jacks, often requiring a dedicated temperature probe for temperature measurements (not included with all multimeters).

5.6 Funció HOLD

Press the 'HOLD' button to freeze the current reading on the LCD display. Press it again to release the hold and resume live readings.

6. Manteniment

6.1 Neteja

Netegeu la c del comptadorasing amb anunciamp drap i detergent suau. No utilitzeu abrasius ni dissolvents. Assegureu-vos que el mesurador estigui sec abans d'utilitzar-lo.

6.2 Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries as described in Section 4.1. Always use new alkaline batteries of the specified type.

6.3 Canvi de fusibles

If the current measurement function stops working, the fuse may need replacement. This typically requires opening the meter's casing. Refer to the meter's internal markings for the correct fuse type and rating (e.g., 200mA/250V for mA range, 10A for 10A range). Only replace with a fuse of the identical type and rating.

6.4 Emmagatzematge

If the meter is not used for an extended period, remove the batteries to prevent leakage and damage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Solució De Problemes

• Sense pantalla / Pantalla tènue: Check battery installation. Replace batteries if low battery indicator is present or if display is faint.
• Lectures incorrectes: Ensure the function switch is set to the correct range. Check test lead connections. Verify the circuit is properly connected.
• La mesura actual no funciona: Comproveu el fusible. Substituïu-lo si està fundit (vegeu la secció 6.3).
• 'OL' or '1' on Display: Indicates overload or out-of-range measurement. Select a higher range or verify circuit connection.
