Abstract

1,112,401. Electric meters. BROWN, BOVERI & CIE, A. G. July 14, 1966 [ Sept. 2, 1965], No. 31734 /66. Heading G1Q. Each of the pairs 4 to 7 input terminals is connectible to the digital meter 1 by operation of associated push-button switches 8 to 11 which are so inter-locked that only one input at a time can be connected. Each input may bare its own range selector switch, 12 to 15, and there may also be an A. C. or D. C. selector 20 and a filter circuit switch 21.
