12. What should I do if the readings appear incorrect?
If measurements seem unusual, check the setup before assuming the instrument is faulty.
Try these steps:
- Confirm the selected measurement mode.
- Check probe and test-lead connections.
- Verify the measurement range.
- Inspect the probe or cable for damage.
- Make sure the circuit under test has a suitable reference or ground connection.
- Restart the instrument if necessary.
- Compare the reading with a known reference when appropriate.
For oscilloscope measurements, incorrect probe connections or unsuitable scale settings can also produce confusing waveforms.
