Capacitance, Resistance and Inductance Substitution Boxes

Direct reading, side-by-side thumbwheel switches are color-coded to separate ranges. Resistance switching is continuous, will not break circuit. Compact, portable, ruggedly built. 124-104 is a combination of the 123-494 and 513-200 in a single convenient package. It features a shorting link to allow both sections to be coupled, the resistance and capacitance may be used independently, in series, or in parallel. Inductance from 1mH to 999mH with 2% tolerance. Resistance from 1 ohm to 9,999,999 ohms with 1% tolerance; 1/2 watt rating, capacitance from 100pF to 99.9999µF with 4% tolerance. Precision versions of above capacitance and resistance boxes are available with improved accuracy: resistance box 0.1%, capacitance box 1%.
