The RS-500 Resistance Substitution Box is a convenient
instrument for determining the desired resistance values in circuits
under design or test. The resistance obtainable is from 0 ohm to
11,111,110 ohm in 1 ohm steps. All resistors are precision 1% resistors.
All of the resistors are wired in series. A switch on the front panel
shorts each resistor. Putting the switch in the ON (up) position
removes the short and places the resistor across the output
terminals. The two green binding posts serve as the output
terminals. To place any resistance across the output terminals turn
ON those switches that add up to the desired resistance.
For example, for 5,071 ohm, turn on the 3k ohm, 2k ohm, 40 ohm, 30 ohm and 1 ohm switches.
