Period

Canada

Used in Canada.

Function

Used to measure charging current. For charging radio batteries from a wind powered generator.

Technical

Panel DC Ammeter for battery testing, probably iron vane (movable iron) mechanism because of the cheapness of the instrument. Good example of a generic, mass produced, low cost, but sturdy meter that has low accuracy yet is suitable for the battery management tasks it is used for. Also a good example of early radio enthusiasts having to often adopt equipment from other sources to suit their purposes.
