Extech 380405 Capacitance Substitution Box

Product Description The Extech 380405 Capacitance Decade Box is very popular for product design testing and calibration because it can be substituted into a circuit and function in the place of any component with a standard value easily. Alternatively, it can be used to identify the best value for circuit operation then read that value from the switches. A capacitor of the size indicated by the decade box switches can then be put into the circuit. From the Manufacturer Capacitance substitution box is excellent for circuit development. It features 5 decades substitution from 100pF to 11,111?F. 5% accuracy. 3 binding posts permit isolated substitutions and grounding the case separately.
