ABSTRACT:
A multipoint recorder of the type used to monitor a number of measuring instruments and including a mechanism having a group of contacts for sequentially selecting signals from a number of measuring points, a self-balancing circuit having a balancing motor for intermittently measuring each of said signals, and an indicating and recording mechanism operated in synchronism with said selection mechanism for indicating and recording, e.g., on a strip chart, the group of measurements supplied by said self-balancing circuit. The multipoint recorder is characterized by a group of auxiliary contacts in said selection mechanism interspersed with the group of measuring point selection contacts, said auxiliary contacts being switched with a given delay behind switching of the measuring point selection contacts so that the auxiliary contacts are sequentially closed as the selection mechanism switches between measuring point selection contacts. In response to the switching of said auxiliary contacts, means are provided for locking said balancing motor or performing alarm operations or other functions while the selection mechanism switches from one measuring point to another.
