Abstract

PURPOSE: To facilitate the adjustment and to improve the eliminating performance by connecting a finely adjusting resistor, which is changed over by a switch, in parallel with a roughly adjusting resistor.
CONSTITUTION: When twin change-over switches 3 and 3' are connected with contacts a and a'. a main sliding resistor 1, an auxiliary sliding resistor 5 and a finely adjusting fixed resistor 7, 7' and 6 are connected in parallel so that the eliminating rought adjustment of the stray current through DC power sources 4 and 4' can be accomplished to a satisfactory extent by the adjustment of the resistor 5 in addition to the resistor 1. If the switches 3 and 3' are connected with the contacts b and b', a fine adjustment is carried out through a circuit consisting of the resistors 6, 7 and 7'. If, in this instance, the resistance of the resistor 5, which is lower one or two units than that of the resistor 1, is made substantially equal to the resistor 6, and if the resistance of the resistors 7 and 7' is made higher one or two units than that of the resistor 6, the internal resistance during the rought and fine adjustments can be substantially equal so that the deterioration in erpformance during the elimination can be prevented
