Abstract
A medical apparatus comprising an apparatus body and a terminal instrument which operates when receiving a terminal output which is an electric or electromagnetic output. The terminal instrument is provided with an installed cell of predetermined capacity and the apparatus body is provided with a circuit for measuring the electromotive force (emf) of the installed cell while discharging the emf via a predetermined resistance as the terminal instrument is used. A comparator compares the emf with a standard voltage and the output command is blocked from the primary control section when the emf of the installed cell is below the standard voltage. Moreover, an alarm is generated when the emf of the installed cell is below the standard voltage level during the use of the terminal instrument.
