3. Подешавање

3.1 Инсталација батерије

The multimeter requires 2 AAA batteries (not supplied) for operation. Follow these steps to install them:

1. Пронађите одељак за батерије на задњој страни мултиметра.
2. Loosen the screw securing the battery cover using a Phillips head screwdriver.
3. Скините поклопац батерије.
4. Insert 2 AAA alkaline batteries, ensuring correct polarity (+ and -).
5. Вратите поклопац батерије и затегните завртањ.

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

4. Упутство за употребу

4.1 Укључивање/искључивање

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 Основна мерења

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

4.2.1 ВолtagМерење (AC/DC)

За мерење волtage:

1. Rotate the knob switch to the 'V=' (DC Voltagе) или 'V~' (AC Voltagд) положај.
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. Прочитајте књtagе вредност на ЛЦД екрану.

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

4.2.2 Мерење отпора (Ω)

Да бисте измерили отпор:

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. Очитајте вредност отпора на ЛЦД екрану.

4.2.3 Continuity Test (♫)

Да бисте извршили тест континуитета:

1. Rotate the knob switch to the '♫' (Continuity) position.
2. Повежите мерне каблове преко кола или компоненте.
3. If there is continuity (low resistance), the multimeter will emit an audible beep.

4.2.4 Diode Test (†)

Да бисте тестирали диоду:

1. Rotate the knob switch to the '†' (Diode) position.
2. Спојите црвени мерни кабл на аноду, а црни мерни кабл на катоду диоде.
3. Посматрајте напред волtage drop on the display. Reverse the leads to check for open circuit (OL) in reverse bias.

4.2.5 Мерење капацитивности (F)

За мерење капацитивности:

1. Rotate the knob switch to the 'F' (Capacitance) position.
2. Уверите се да је кондензатор потпуно испражњен пре повезивања мерних каблова.
3. Спојите мерне каблове преко кондензатора.
4. Прочитајте вредност капацитивности на ЛЦД екрану.

4.2.6 Frequency and Duty Cycle Measurement (Hz/DUTY)

Да бисте измерили фреквенцију или радни циклус:

1. Rotate the knob switch to the 'Hz/DUTY' position.
2. Повежите мерне каблове са извором сигнала.
3. The display will show the frequency (Hz). Press the 'RANGE' button to toggle to duty cycle measurement.

4.3 Функција задржавања података

Press the 'H' (Data Hold) button to freeze the current reading on the display. Press it again to release the hold and resume live readings.
