Our shop is equipped with 2 types of indicators: Dial indicators (also called drop indicators), and Dial Test Indicators (DTI's). ====General==== * Indicators are used in various ways with magnetic indicator arms, or on the [[surface_plate|Surface Plate]], in conjunction with a [[etalon_height_gauge|Height Gauge]] or a [[surface_gauge|Surface Gauge]]. * Indicators can also be used on machines, in special holders for either the [[bridgeport_series_1|Mill]] or [[mini_lathe|Lathe]]. * Indicators can be used to measure height, flatness, parallelism, perpendicularity, and more! ====Dial Indicators==== * Read in thousandths of an inch (1 division = 0.001", 1 rotation = 0.100") * Can be Zeroed by turning the dial face until the Zero aligns with the needle * Interchangeable tips * Can be attached via lug on back, or using a snug on the stem (stem is 3/8" diameter) ====Dial Test Indicators==== * Read in either half-thousandths (1 division = 0.0005"), or ten-thousandths (1 division = 0.0001") * Can be Zeroed by turning the dial face until the Zero aligns with the needle * Lever arm probe can be positioned as desired * Can be attached via dovetails on indicator body, or by attachable stem (2 stems, 5/32" and 3/8")
