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

4. Istruzzjonijiet Operattivi

4.1 Power On/Off

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 Kejl Bażiku

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

4.2.1 TitjiratagKejl elettroniku (AC/DC)

Biex tkejjel il-voltage:

1. Rotate the knob switch to the 'V=' (DC Voltage) or 'V~' (AC Voltage) pożizzjoni.
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. Aqra l-voltage valur fuq il-wiri 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 Kejl tar-Reżistenza (Ω)

Biex tkejjel ir-reżistenza:

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. Aqra l-valur tar-reżistenza fuq id-displej LCD.

4.2.3 Test tal-Kontinwità (♫)

Biex twettaq test tal-kontinwità:

1. Rotate the knob switch to the '♫' (Continuity) position.
2. Qabbad il-wajers tat-test madwar iċ-ċirkwit jew il-komponent.
3. If there is continuity (low resistance), the multimeter will emit an audible beep.

4.2.4 Diode Test (†)

Biex tittestja dajowd:

1. Rotate the knob switch to the '†' (Diode) position.
2. Qabbad il-wajer tat-test aħmar mal-anodu u l-wajer tat-test iswed mal-katodu tad-dijodu.
3. Osserva l-quddiem voltagqatra e fuq id-displej. Dawwar il-wajers biex tiċċekkja għal ċirkwit miftuħ (OL) f'polarizzazzjoni inversa.

4.2.5 Kejl tal-Kapaċità (F)

Biex tkejjel il-kapaċità:

1. Rotate the knob switch to the 'F' (Capacitance) position.
2. Kun żgur li l-kapaċitatur ikun skarikat kompletament qabel ma tqabbad il-wajers tat-test.
3. Qabbad il-wajers tat-test mal-kapaċitatur.
4. Aqra l-valur tal-kapaċità fuq il-wiri LCD.

4.2.6 Frequency and Duty Cycle Measurement (Hz/DUTY)
