You'll need a dedicated capacitance meter, or a measurement system that is designed to measure capacitance. It will have to be capable of measuring very small values.

The way the tester works is to pass an AC signal through the DUT. Internally, the circuit is a voltage divider or Wheatstone bridge. The signal across the DUT is sampled and compared with the input to determine the drop, which indicates reactive impedance.
