Extech 380400 Resistance Decade Box

Wide-Range Resistance Decade Box The Extech 380400 Resistance 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 quite easily. Alternatively it can also be used to identify the best value for circuit operation and then read that value from the switches. Then a resistor of the size indicated by the decade box switches can then be put into the circuit. The concept of the decade box works well with a number of component types greatly accelerating the trial and error process. However you are likely to find that the arrangement of switches can vary. This device measures 4.6 x 5.7 x 1.4 inches H x W x D and the case may be grounded separately.
