Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

IEEE / ANSI

ANSI/IEEE voltmeter symbol

The voltage-meter form identifies an indicating instrument connected to a documented voltage measurement. Its measurement pair, selected source and any VT ratio must be read separately from the instrument's auxiliary supply.

Drawing use: SLD / Schematic
Application: Metering & protection
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Instrumentation and Sensors functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

A voltage meter displays a quantity; a voltage relay applies an operating criterion and issues an output.

Symbols

Voltmeter

A voltmeter indicates electrical potential difference between its measurement inputs. The drawing identifies the measured conductors and any instrument transformer or selector associated with those inputs.

A distinction that matters

A voltmeter indicates voltage; a voltage relay issues an output according to a voltage condition.
