Claims (1)
調節計において、読出回路には常時接続されるが
書込回路には常開スイツチを介して接続される特
定データ用不揮発性メモリ、及び特定データ書込
時のみ上記常開スイツチを閉成する手段を備えて
なる不揮発性可変定数を有する調節計。 In a controller that has a non-volatile memory in which variable constants are stored, there is a non-volatile memory for specific data that is always connected to the read circuit but is connected to the write circuit via a normally open switch, and a specific data write memory. A controller having a nonvolatile variable constant, comprising means for closing the normally open switch only when the switch is closed.
