Triplett Model 630 Analog Meter

The Triplett Model 630 is a small, durable, analog multimeter. It has been crafted to perform, accurate measurements on all types of electrical and electronic equipment. The indicating portion of the meter is actuated by a taut band suspension movement having a sensitivity of 50 microampere full scale. This movement omits conventional pivots, bearings and hairsprings and provides improved repeatability by eradicating friction between both pivots and bearings. No moving parts are in contact and the elimination of the hairspring prevents both snagging and tangling. The tension spring acts as a built-in shock absorber. In addition, temperature variations will not cause sticky operation of the pointer. The 630 is supplied with test leads with alligator clips and batteries (1.5V and 30V).
