Title
[D8833AAH], Letter from Edison Lamp Co to Thomas Alva Edison, February 3rd, 1888
Editor's Notes
"We send you today a 150 volt indicator and a 1200 volt indicator. Both are battery indicators. When no current is acting on these indicators the screw switch on front must be opened. If it is not the batteries work on closed circuit through the galvanometer and they will use themselves up and be inaccurate."
