1432-L: Difference between revisions

The Type 1432-L is decade resistance box is comprised of four Type [[510]] decade resistance units in series for a total resistance of 111,100 Ω. The [[510]] decade units use an 11 position switch, the first position shorts the decade the following positions increase the resistance by a factor of 1. The decade switch is what's referred to as a make before break configuration, regardless of the position there's always a continuity at it's terminals. The terminals are Type 938 equipped with a shorting link to the case. The decades are housed in an aluminum case shielded and insulated from its resistance terminals.
