The Resistance Substitution Box is a convenient instrument in determining the desired resistance values in
circuits under design or test. The values selected for your resistance substitution box were determined to be
the most commonly used in modern solid-state circuits. The values are from 10
Ω to 1,000kΩ (1 meg) in 24
steps. All resistors are 5% tolerance 1/2 watt.
