MaraMeter Indicating Measuring Instruments M 9-3 Mahr Advantages of the Snap Gage 840 F compared to a Micrometer 1 Reduced Measuring Uncertainity The MaraMeter Indicating Snap Gages have a notably reduced measuring uncertainty in comparison to to a Micrometer. Work piece tolerance in m Measuring Uncertainty U is dependent upon the tolerance of the work piece Better utilization of Work piece tolerance 25 the tolerance zone Example T C m TO Work piece tolerance 25 m Uncertainty range Range of certainty Uncertainty range The measured value in the uncertainty range can lie outside of the tolerance range therefore the utilized tolerance of the Micrometer is reduced to only 32% (8 m). With a MaraMeter Indicating Snap Gage 840 F 83% (20.8 m) of the work piece tolerance can be utilized. U 85 pm (34%) U 85 pm (34%) U 21 pm (84%) Uncertainty range 208 pm (832%) Range of certainty U 21 pm (84%) Uncertainty range Advantage With the Indicating Snap Gage the tolerance zone can be used to far greater extent thus reducing the production costs.
