Owing to the use of an aluminum pointer, a light counterweight is possible, resulting in a light weight of movementand small wear on the pivot jewels. The high torque, in pro-portion to the light weight, insures great accuracy consid-ering their size. Their scales arc 4 in. long., which is practically thesame length as the scales of many 7 in. meters. The fulllength of the pointer shows on the dial, thus making the.

These metersare manufactured by the Westinghouse Electric & Manufac-turing Company. Although somewhat diminutive in size they are not inany sense competitive with many toy meters on the marketbut are designed along strictly scientific lines and possessa high grade of quality.
