Analog meters are characterized by using a point and scale to indicate values.

• A. A point and scale to indicate values
• B. A digital readout
• C. A moving coil
• D. A loud display

Answer: (A)

Analog meters deliver readings with a pointer moving over a fixed scale, so you determine the value by where the needle points on the calibrated marks. That combination—the moving indicator (the point) and the scale—is what allows a continuous, analog display of measurement. A digital readout shows numeric digits instead of a needle on a scale, so it isn’t describing the same display method. The moving coil is a common component inside many analog meters, producing the deflection, but it isn’t what defines an analog instrument since other mechanisms can also create an analog deflection. A loud display isn’t relevant to how the measurement is shown. So the best match is the simple, defining idea: a point and scale to indicate values.
