Q: The multimeter reading is not correct, how to fix it
When reading voltage with a multimeter, you may notice wildly fluctuating or incorrect voltage readings on a known voltage source, usually a sign of a blown internal fuse. At this time, it is necessary to test whether the fuse is connected and replace it according to the fuse recommended by the user manual.
If the fuse blows at a certain current setting, there will be no fluctuation in the test value in the series circuit under test. Please test the fuse again for continuity and replace it according to the fuse recommended by the user manual.
If replacing the fuse doesn't fix the problem, you may need to buy a new multimeter.
