Description
The Extech 380405 decade capacitance box is very popular for product design testing and calibration because it can easily be substituted for a circuit and function in place of any component with a standard value. Alternatively, it can be used to identify the best value for circuit operation and then read that value from the switches. A capacitor of the size indicated by the decade resistance box switches can then be placed in the circuit.
