-
Example of current measure from early electrical infrastructure. Probably sold through Westinghouse Canada in Hamilton. - Function
-
To measure direct current in amperes. - Technical
-
Switchboard meter for direct current with range up to 1200 amps. Larger meter than usual. Example of early meter with complete movement easily removed for repairs, representing the surviving workshop culture of the early 20th century. Flat glass to render the cover visible. Case is soft iron for magnetic shielding. Sometimes hand-marked scales. Classic art nouveau design and decorative features. The arrow of the pointer is perforated, which makes it more visible from far away. The arrow is thicker than similar Weston meters from the same period, as is the arm of the pointer. Having heavier movable parts meant that the pointer would have more momentum and thus over swing more, and take longer to stabilize. - Area Notes
