What is measuring voltage?Show answer
To measure the potential difference across a component:
What is measuring current?Show answer
To measure the current through a part of the circuit:
What is measuring resistance?Show answer
A related setting is the continuity test, which beeps when there is a low-resistance connection, useful for checking that two points are joined or a wire is unbroken.
What is choosing the range?Show answer
If the meter is not auto-ranging, choose a range just above the value you expect. Too low a range over-reads or shows an overload; too high a range loses precision. If unsure, start on the highest range and step down until you get a clear reading.
