Abstract
PURPOSE:To provide a checker high enable inspection of not only the battery and a load section thereof by connecting a given detection means to a checking detection indicating circuit with a hysteresis characteristic through a mutual interference prevention element. CONSTITUTION:A primary coil 26 of a transformer 25 for signal detection is connected across both ends of a current limitting capacitor of a transistor inverter 10 while the secondary coil 27 is provided with a rectifier 28 which is connected to the input end of a checking detection indicating section comprising a ramda diode 20 of a battery checker 1 and the like through a resistance 29, a capacitor 30, a mutual interference prevention diode 31 or the like. In this manner, an inverter checker VI is formed. A voltage of a battery 9 and a lower voltage from amonug output voltages corresponding to a voltage at both ends of the current limitting capacitor 24 in proportion to the loop current of a fluorescent lamp from the inverter checker VI are applied on the input end of the battery checker V. Accordingly, in addition to abnormal reduction in the capacity of the battery 9, the abnormalty of the inverter 10 can be checked.
