Warning: Always ensure the multimeter is turned OFF and disconnected from any circuits before opening the battery compartment.

4. Instruccions de funcionament

4.1 Encès/Apagat

To turn on the multimeter, rotate the knob switch from the 'OFF' position to any desired measurement function. To turn off the multimeter, rotate the knob switch back to the 'OFF' position. The device features an automatic power-off function to save battery life if left idle for a period.

4.2 Mesures bàsiques

The DM Mini is an auto-ranging multimeter, simplifying operation by automatically selecting the appropriate measurement range.

4.2.1 voltagMesura (CA/CC)

Per mesurar voltage:

1. Rotate the knob switch to the 'V=' (DC Voltage) or 'V~' (AC Voltage) posició.
2. Connect the red test lead to the positive (+) side of the circuit and the black test lead to the negative (-) side (for DC) or across the points for AC.
3. Llegeix el voltage valor a la pantalla LCD.

Figura 4.1: Examples of measuring DC voltage from a 9V battery and AC voltage from a power outlet using the multimeter.

4.2.2 Mesura de resistència (Ω)

Per mesurar la resistència:

1. Rotate the knob switch to the 'Ω' (Resistance) position.
2. Ensure the circuit is de-energized before connecting the test leads across the component to be measured.
3. Llegiu el valor de la resistència a la pantalla LCD.

4.2.3 Prova de continuïtat (♫)

Per realitzar una prova de continuïtat:

1. Rotate the knob switch to the '♫' (Continuity) position.
2. Connecteu els cables de prova a través del circuit o component.
3. If there is continuity (low resistance), the multimeter will emit an audible beep.

4.2.4 Diode Test (†)

Per provar un díode:

1. Rotate the knob switch to the '†' (Diode) position.
2. Connecteu el cable de prova vermell a l'ànode i el cable de prova negre al càtode del díode.
3. Observeu el vol endavanttage drop on the display. Reverse the leads to check for open circuit (OL) in reverse bias.

4.2.5 Mesura de la capacitança (F)

Per mesurar la capacitat:

1. Rotate the knob switch to the 'F' (Capacitance) position.
2. Assegureu-vos que el condensador estigui completament descarregat abans de connectar els cables de prova.
3. Connecteu els cables de prova a través del condensador.
4. Llegiu el valor de la capacitat a la pantalla LCD.

4.2.6 Frequency and Duty Cycle Measurement (Hz/DUTY)

To measure frequency or duty cycle:

1. Rotate the knob switch to the 'Hz/DUTY' position.
2. Connecteu els cables de prova a la font de senyal.
3. The display will show the frequency (Hz). Press the 'RANGE' button to toggle to duty cycle measurement.

4.3 Funció de retenció de dades
