PURPOSE: To improve the function of a safety measure and the like by performing at least one demonstration among a discharge demonstration of driving a micropump for the specified time, an alarm demonstration of life advance notice and life end alarm, and an action confirming sound demonstration at the normal action time of the micropump.
CONSTITUTION: A CPU 30, after being system-reset, rings a bell upon detecting the L→H of an OPIN terminal. When a switch A is closed, a discharge demonstration corresponding to the set discharge is performed, and driving pulses by one cycle part of the set discharge are outputted to a piezoelectric element 11a to drive a micropump 11, thus displaying the discharge demonstration. When a switch B is closed, an alarm demonstration of life advance notice and life end alarm is performed, and an alarm bell is rung, displaying alarm. When a switch D is closed, an action confirming sound demonstration on whether or not the action is normal is performed, and a normal time action confirming sound is rung, leaving the display in the initial state. A user can therefore handle this micropump at ease.
