Abstract
High precision film resistors are designed as a main resistive element corresponding to half the total value associated with five additional resistive elements the values of each of which are successively half of the value of the preceding one plus one resistive element of the same value as the smallest element of the five above mentioned elements, each of the additional element is originally short-circuited, adjustment being performed by cancelling at least one of the short circuits. This design of the resistive elements allows a reduced number of short circuit suppressions than previously used designs with the same precision.
