## Symbol convention

Convention: IEC
Form: Combined line and phase voltmeter selector
Autodesk IEC-60617 Symbol Preview — Measurement-selection and mechanically operated switch forms; vendor family reference, not certified IEC geometry or database identifier.

This representation identifies a selector covering phase-to-phase and phase-to-neutral voltage measurements.

## What it represents

This representation identifies a selector covering phase-to-phase and phase-to-neutral voltage measurements. One selector covers both line-to-line and line-to-neutral measurements. The measurement function changes with position even though the meter and its physical terminals remain the same.
List the selected conductor pair or phase/reference path for every position. Use the selected switch’s contact programme instead of inferring connections from the face labels alone.

## How to read it

- Provide a position table specifying each measurement path.
- The symbol cannot replace the actual switch contact programme.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Provide a position table specifying each measurement path.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

The symbol cannot replace the actual switch contact programme.
