Informationen:
                                    The MODEL DT 72A DEKATRAN DECADE TRANSFORMER is a laboratory
standard divider for establishing either voltage or current
ratios at audio frequencies.

The DEKATRAN circuit is an auto-transformer with a variable
tap. The tap position is indicated by the dial reading which
gives the ratio of output turns to input turns. Additional
windings extend the ratio above and below the input so that
voltage ratios of -0. 1 and +1. 1 are available.

The accuracy of the DEKATRAN is established by
intercomparisons over a wide range of frequencies and dial
settings, traceable to a special NBS -certified transformer.
