• To activate the LCD backlight, press the LED button. Press it again to turn off the backlight.
• To power off the multimeter, rotate the switch back to the "OFF" position.

5. Instruccions de funcionament

This section details how to perform various measurements with your multimeter.

5.1. Mesura de la tensió de CCtage (V—)

1. Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
2. Rotate the switch to the desired "V—" (DC Voltage) range. Start with the highest range if the voltage es desconeguda.
3. Connect the test probes in parallel across the component or circuit to be measured. The red probe to the positive side, black to the negative.
4. Llegeix el voltage valor a la pantalla LCD.

5.2. Mesurar AC Voltage (V∼)

1. Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
2. Rotate the switch to the desired "V∼" (AC Voltage) range. Start with the highest range if the voltage es desconeguda.
3. Connect the test probes in parallel across the AC source or component.
4. Llegeix el voltage valor a la pantalla LCD.

5.3. Measuring DC Current (A—)

Precaució: Always connect the multimeter in series with the circuit when measuring current. Never connect it in parallel across a voltage source, as this can damage the multimeter and the circuit.

1. For low current (mA): Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
2. For high current (10A): Introduïu el cable de prova negre al COM presa i el cable de prova vermell al 10A jack.
3. Rotate the switch to the appropriate "A—" (DC Current) range (e.g., 200mA, 10A).
4. Open the circuit where you want to measure current. Connect the multimeter in series, ensuring the current flows through the multimeter.
5. Llegiu el valor actual a la pantalla LCD.

5.4. Mesura de la resistència (Ω)

Precaució: Ensure the circuit or component is completely de-energized before measuring resistance. Measuring resistance on a live circuit can damage the multimeter.

1. Introduïu el cable de prova negre al COM presa i el cable de prova vermell al VΩmA jack.
2. Rotate the switch to the "Ω" (Resistance) range. Start with a higher range if the resistance is unknown.
3. Connect the test probes across the component whose resistance you want to measure.
4. Llegiu el valor de la resistència a la pantalla LCD.

5.5. Prova de continuïtat (♫)

The continuity test checks for a complete electrical path between two points. An audible buzzer will sound if continuity is detected.

2. Rotate the switch to the continuity (♫) posició.
3. Toqueu les sondes de prova als dos punts on voleu comprovar la continuïtat.
4. If a continuous path exists (low resistance), the buzzer will sound, and the display will show a low resistance value. If no continuity, the display will show "OL" (Open Line).

5.6. Prova de díodes (→|—)

La prova del díode mesura el volum directetagcaiguda e d'un díode.
