Extech Instruments 380400 CAL DU Datasheet & Stock

The 380400 CAL DU from Extech Instruments is a resistance decade box. It 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. Then, a resistor of the size indicated by the decade box switches can be put into the circuit. This device offers 7 decades of resistance ranges from 1 to over 11Mohm. Slide switches allow easy addition and subtraction of resistance values.
