What it represents
The preset-adjustment capacitor form identifies an adjustable capacitive parameter. Its permitted range and commissioning or operational adjustment method come from the component data rather than from an assumed interpretation of the adjustment mark.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Determine whether adjustment is a preset or a normal operational control.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- State capacitance range
- Reference adjustment method
- Identify circuit terminals
A distinction that matters
Capacitive adjustment changes a circuit parameter; it is not a switched connection between two independent circuits.
