What is a Capacitance Meter?

Capacitance Meter Definition

A capacitance meter is a device used to measure the capacitance of discrete capacitors.

Working Principle

It operates based on the proportional relationship between capacitance and a time constant.

Measurement Method

Capacitance is measured using a 555 timer by calculating the time period of oscillations.

Role of 555 Timer

The 555 timer acts as an astable multivibrator, with its frequency determined by the unknown capacitance (CX).

Practical Use

Proper shielding of leads is necessary to avoid instability in low capacity measurements.
