Analogue indication multi-measuring instrument used as demonstration unit for teaching experiments - has housing with scale window in which holding frame with several scales is rotatable arranged around axis
The scales (36,40) are uniformly distributed over the circumference and are held by the holding frame (28), and appear at the scale window (26) with rotation around spindle (30). Several identical scale carriers (32-35) are provided, each of which carries at least two scales (38,40). Each scale carrier in the holding frame is rotatable about a carrier axle (36), which is positioned at a pitch circle around the spindle (30), and runs parallel to this. The stop (48) is fixed at a distance from the pitch circle at the housing (20-24), which is positioned in the movement range of the scale carriers, which with rotation of the holding frame can make contact with the stop (48), and thereby successively effecting a swivel movement of each scale carrier around the respective carrier axle (36). A guide for the scale carrier is provided at the housing behind the scale window, which with rotation effects an alignment of the respective indicated scale. USE/ADVANTAGE - E.g. for demonstrations. Type unit further developed,so that without requiring larger space, larger no of scales can be arranged at holding frame, without reducing size of scales.
