4. Nastavitev

4.1 Namestitev baterije

1. Prepričajte se, da je multimeter izklopljen in odklopite vse merilne kable.
2. Poiščite pokrovček predalčka za baterije na zadnji strani multimetra.
3. Odvijte pritrdilni vijak (vijake) in odstranite pokrov.
4. Vstavite dve 1.5 V bateriji AAA in pri tem upoštevajte pravilno polarnost (+ in -), kot je označeno v notranjosti predala.
5. Namestite pokrov predalčka za baterije in ga pritrdite z vijakom(-i).

4.2 Priključitev merilnih vodnikov

Priključite merilne kable na ustrezne vhodne priključke na multimetru:

• Vstavite črna merilni kabel v COM (navadni) priključek.
• Za večino meritev (Voltage, Resistance, Diode, Continuity, Temperature, Battery Test), insert the rdeča merilni kabel v VΩmA jack.
• For high current measurements (up to 10A), insert the rdeča merilni kabel v 10A jack.

5. Navodila za uporabo

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

5.1 Merjenje DC Voltage (V=)

1. Set the rotary switch to the desired V= range (e.g., 20V for measuring up to 20V DC).
2. Rdečo merilno vez priključite na pozitivno (+) stran vezja, črno merilno vez pa na negativno (-) stran.
3. Preberite zvtage vrednost na zaslonu.

5.2 Merjenje AC Voltage (V~)

1. Set the rotary switch to the desired V~ range (e.g., 200V for measuring up to 200V AC).
2. Priključite merilne kable na izmenični tok (AC volt)tage vir.
3. Preberite zvtage vrednost na zaslonu.

5.3 Merjenje enosmernega toka (A=)

1. Pomembno: Preden multimeter priključite zaporedno, izklopite napajanje tokokroga.
2. Set the rotary switch to the desired A= range (e.g., 200mA or 10A). Remember to move the red lead to the 10A jack for high current.
3. Odprite tokokrog, kjer želite izmeriti tok.
4. Connect the multimeter in series with the circuit, ensuring the current flows through the multimeter.
5. Priklopite napajanje na vezje in na zaslonu odčitajte trenutno vrednost.

5.4 Merjenje upornosti (Ω)

1. Pomembno: Pred merjenjem upornosti se prepričajte, da je vezje brez napetosti in da so vsi kondenzatorji izpraznjeni.
2. Set the rotary switch to the desired Ω obseg.
3. Merilne kable priključite na komponento, ki jo želite izmeriti.
4. Na zaslonu preberite vrednost upora.

5.5 Test diod (→|)

1. Pomembno: Prepričajte se, da je dioda odklopljena iz vezja.
2. Vrtljivo stikalo nastavite na Diodni test položaj.
3. Rdeči merilni kabel priključite na anodo, črni pa na katodo diode. Na zaslonu se bo prikazala napetost v smeri naprej.tage padec.
4. Zamenjajte žice. Na zaslonu bi moral biti napis "OL" (odprta zanka), če je dioda v redu.

5.6 Preizkus neprekinjenosti ())))

1. Pomembno: Prepričajte se, da je tokokrog izklopljen.
2. Vrtljivo stikalo nastavite na Test kontinuitete položaj.
