Abstract

PURPOSE:To move a needle in a prescribed display band, by separating the display part of a voltmeter with an extended measure into upper and lower display bands and changing the magnifying power and the voltage division ratio for a voltmeter between the no-load case and the on-load case. CONSTITUTION:A voltage measuring circuit consisting of a voltage dividing resistance 6 and a constant voltage element 4 is connected to a storage battery 1 by the operation of a switch 3 in the no-load case of the storage battery 1, and a voltage measuring circuit consisting of voltage dividing resistances 6 and 7 and a constant voltage element 5 is connected to the storage battery 1 in the on-load case. A volmeter 8 is connected to both ends of the voltage dividing resistance 6 and is provided with an extended measure. The display part of the voltmeter 8 is separated to a display band 12 for no-load case where the specific gravity of the electrolyte and the capacity of the storage battery are displayed with different colors and a display band 13 for on-load case where the voltage of the storage battery or the capacity of the storage battery is displayed with different colors. Thus, the magnifying power and the voltage division ratio of voltage measuring circuits are adjusted to give functions as a voltmeter and a capacity meter to one voltmeter, and respective values are displayed with their full scale.
