What it represents
An adjustable capacitor provides a documented variable capacitance. Its control or preset adjustment is specified separately from the two main circuit terminals.
How to read it
- Identify whether adjustment is operational or a commissioning preset.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- State capacitance range
- Show circuit terminals
- Reference adjustment method
A distinction that matters
Adjustable capacitance changes a capacitive parameter; it is not an adjustable resistor.
