4. Konfigurimi

4.1 Instalimi i baterisë

1. Sigurohuni që multimetri të jetë i fikur.
2. Gjeni ndarjen e baterisë në pjesën e pasme të matësit.
3. Përdorni një kaçavidë për të liruar vidën që siguron mbulesën e baterisë.
4. Hiqni kapakun e baterisë.
5. Insert the specified batteries (e.g., 4 x AAA batteries) observing the correct polarity (+/-).
6. Zëvendësoni kapakun e baterisë dhe shtrëngoni mirë vidën.

4.2 Lidhja e Testimit të Kabllit

Always connect the test leads to the appropriate input jacks for the measurement you intend to perform. Incorrect connection can lead to damage to the meter or personal injury.

• Për shumicën e matjeve (Vëll.tage, Resistance, Continuity, Diode, Capacitance, Frequency), connect the black test lead to the COM jack and the red test lead to the VΩHz krik.
• For current measurements (mA/µA), connect the black test lead to the COM jack and the red test lead to the mAµA krik.
• For high current measurements (up to 10A), connect the black test lead to the COM jack and the red test lead to the 10A MAX FUSED krik.

5. Udhëzimet e funksionimit

This section outlines the basic steps for performing common measurements with your U1242C DMM.

5.1 Matja e AC/DC Voltage

1. Kthejeni çelësin rrotullues në vëllimin e dëshiruartage range (V~ for AC, V- for DC). The meter may have an auto-ranging feature.
2. Lidhni plumbin e provës së zezë me COM jack and the red test lead to the VΩHz krik.
3. Lidhni sondat e provës paralelisht në të gjithë qarkun ose komponentin që do të matet.
4. Lexoni vëllimintage vlera në ekran.

5.2 Measuring AC/DC Current

CAUTION: Never connect the meter in parallel with a voltage source when measuring current. This can blow the fuse or damage the meter.

1. Turn the rotary switch to the desired current range (A~ for AC, A- for DC, or mA/µA ranges).
2. Lidhni plumbin e provës së zezë me COM krik.
3. For mA/µA measurements, connect the red test lead to the mAµA jack. For 10A measurements, connect the red test lead to the 10A MAX FUSED krik.
4. Open the circuit where current is to be measured and connect the meter in series with the circuit.
