The Circuit Diagram of Capacitance Meter and The Explanation

This is a project to create the instrument capable to measure all but the largest capacitors used in radio circuits. Most variable capacitors aren’t marked with their values, unlike variable resistors. The markers of capacitors from salvaged equipment often rub off unintentionally. This project will prove quite useful to the constructor, antenna experimenter, or vintage radio enthusiast.


Position a has a range of 1 uF.

Position b has a range of 100 nF.

Position c has a range of 10 nF.

Position d has a range of 1 nF.

Position e has a range of 100 pF.

Use the X10 switch to measure up to 10 uF and use X0.5 switch for better readings on low values.
