notes: label: Description (Brief)
content: This bridge and testing set consists of an instrument with brass fittings in a wooden case with a lid. Marked: "Queen & Co. / Makers / Phila."; and "Queen & Co. / The Queen Acme Portable Testing Set. #1560." This is a bridge and testing set incorporating a self-contained galvanometer and plug connections. The resistors are not arranged in decades, but in series somewhat like the weights of a balance, namely. 1, 2, 5, 10, etc., ohms to 5,000 ohms. It would seem strange that at this period (1903). when the set was designed, it was not provided with a decade arrangement of resistors, which idea was a great improvement and was old at that time. Adjusted completed 30 October 1903.
