4. Udhëzimet e funksionimit
This section details how to use the VOLTCRAFT VC276 for various measurements.
4.1 Ndezja/Fikja dhe Zgjedhja e Funksionit
- Turn the rotary dial from the "OFF" position to the desired measurement function to power on the device.
- To power off, turn the rotary dial back to the "OFF" position.
- Use the "SELECT" button to cycle through different measurement modes within a single rotary dial position (e.g., AC/DC voltage, diodë/vazhdimësi).
4.2 VëlltagMatja e e-së (AC/DC)
- Set the rotary dial to the "V" position.
- Lidhni prizën e zezë me COM and the red lead to VΩHz.
- Use the "SELECT" button to choose between AC (~) or DC (---) voltage.
- Connect the test probes in parallel to the circuit or component to be measured.
- Lexoni vëllimintage vlera në ekran.
4.3 Matja e rrymës (AC/DC)

6. Troubleshooting
This section addresses common issues you might encounter with your VOLTCRAFT VC276 multimeter.
| Problem | Shkaku i mundshëm | Zgjidhje |
|---|---|---|
| Pa ekran ose ekran i zbehtë | Low or dead batteries. Device is off. | Replace batteries (see Section 3.2). Turn the rotary dial to a measurement function. |
| Lexime të pasakta | Incorrect function selected. Test leads incorrectly connected. Probes not making good contact. Measuring a live circuit for resistance. | Verify the rotary dial and "SELECT" button settings. Ensure leads are in correct jacks (acoustic alarm will sound if incorrect). Check probe contact. Always de-energize circuits before resistance measurement. |
| Acoustic alarm sounds | Test leads are inserted into the wrong jacks for the selected function. | Re-insert test leads into the correct input jacks according to the selected measurement function. |
| "OL" or "OVER" displayed | Measurement value exceeds the selected range. Open circuit (for continuity/resistance). | The device is autoranging, so this usually indicates an out-of-range value. For resistance/continuity, check for an open circuit. |
