Why is my multimeter displaying a negative number?

Unexpected negative readings (problems): This is the most common “negative reading” scenario – about 60% of cases. You’re measuring DC voltage and the display shows a negative number. This is completely normal and simply means your probes are reversed relative to the polarity of the voltage you’re measuring. The multimeter math: Example scenarios:

How do you know if a battery is positive or negative?

If you measure this difference, your multimeter expects to see a positive value if its red (positive) lead is on the battery’s positive terminal and its black (negative/common) lead is on the battery’s negative terminal. The crucial point here is that voltage is a *relative* measurement. It’s always measured between two points.

What does a negative voltage reading mean?

Expected negative readings: Unexpected negative readings (problems): This is the most common “negative reading” scenario – about 60% of cases. You’re measuring DC voltage and the display shows a negative number. This is completely normal and simply means your probes are reversed relative to the polarity of the voltage you’re measuring.

How do I measure a negative voltage on a multimeter?

When measuring these circuits, connecting your multimeter’s black lead to the common ground and your red lead to the negative voltage rail will correctly display a negative value (e.g., -15V). This is the expected and desired reading.
