61.008. Pocket Voltmeter for 3 volts, Figure, electro-magnetic system with aperiodic 

 adjustment 



A voltmeter preferably of the pocket form is visod for ascertaining the state of charge of 

 the accumulator. The voltmeter has a spear which is firmly placed on one terminal of the cell, while 

 a second spear attached to the short length of flexible is placed in contact with the other terminal.
