The calibrated Mitutoyo 543-392CAL Absolute Digimatic digital indicator gauge, ID-C series, is for measuring short, linear distances in mechanical engineering, machining, and manufacturing applications. It has a measurement range of 0 to 0.5" (0 to 12.7mm), a resolution of 0.00005" (0.001mm), and an accuracy of + or - 0.0001". The LCD screen displays measurements in inches and metric units. The indicator has a go/no-go display that lights green or red, respectively, when upper and/or lower tolerances have been set, and the result can be displayed in full-size characters. The face of the indicator can be rotated 330 degrees for reading from different directions. This unit has a 3/8" diameter stem and a #4-48 UNF contact point thread mount. It has a lug back for mounting from the rear of the indicator. This model is Ingress Protection certified IP42 for protection against objects greater than 1mm and dripping water. Mitutoyo calibrated tools include a Certificate of Calibration that provides evidence that the tool has been calibrated and is within allowable error specifications. Mitutoyo calibrated tools are certified by Mitutoyo's American Association for Laboratory Accreditation-accredited calibration laboratory (A2LA Certificate #750-01) to the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) 17025 International Standard for testing and calibration laboratories.
Additional functions for this indicator include origin set, preset, zero set, counting direction switching, and alerts for low voltage, counting value composition, overflow, and tolerance limit setting errors. An Absolute electrostatic capacitance-type linear encoder helps prevent overspeed errors for taking accurate measurements. The measuring force is 1.5 Newtons (N) or less. It has a battery life of approximately 7,000 hours of normal use. This unit comes with a SR44 battery. This gauge offers serial data output (using optional SPC cables, sold separately), which increases speed and reliability of digital measurement records.

Indicator gauges, also called gages or dial indicators, are precision instruments that measure short linear distances. They are commonly used for detecting deviations from tolerance limits, such as the amount of surface distortion, or runout, on a round or cylindrical workpiece. They have two styles: digital indicator gauges and dial indicator gauges. Digital indicator gauges use an electronic sensor and display measurement through an LCD or other digital display. Dial indicator gauges measure through a spring-loaded plunger driven into its shaft. The pointer on the dial display marks the degree the plunger is depressed, while an additional turn counter may track the number of times the pointer has spun around the dial. For all types of indicator gauges, runout is typically measured when the tip of the plunger (the point) is held perpendicular to the rotating workpiece. Indicator gauges are typically used in manufacturing, machining, and mechanical engineering.
Mitutoyo manufactures precision measuring tools, metrology equipment, and related systems. The company, founded in Tokyo in 1934, formed Mitutoyo America Corporation in 1963 with headquarters in Aurora, IL.
