Abstract
PURPOSE: To easily and accurately judge the time of renewal of a battery, by adapting a light-emitting element to flash with an output from a multivibrator through an operational amplifier which receives as inputs a stabilized voltage and a voltage in proportion to the voltage of the battery.
CONSTITUTION: A voltage obtained by dividing a power source voltage E by resistors 6, 7 is input into one input terminal 5a of an operational amplifier 5, and a stable voltage set by a resistor 8 and a Zener diode 9 into the other input terminal 5b. An output terminal 5c of the operational amplifier 5 is connected through a resistor 10 to a transistor 16 in a multivibrator consisting of resistors 10W13, capacitors 14, 15, transistors 16, 17 and a light-emitting diode 18. In the above structure, the light-emitting diode 18 flashes or is turned off when the voltage of the power source battery E has dropped to a limit level, so that the correct time of renewal of the battery can be known.
