It delivers an accuracy of 0.0003 inches and a resolution of 0.000050 inches, making it suitable for precision depth measurement in machining, inspection, and fabrication environments. The gage features a 2.5-inch base, a solid rod design with an included extension rod, and a built-in SPC output function for data logging. It runs on a single SR44 silver oxide battery, which is included. Machinists, quality control technicians, and precision fabricators are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThe 547-257A is used in production and inspection settings where accurate depth readings are required on bores, slots, steps, and recesses. The inch\/mm conversion function allows the user to switch between measurement systems without a separate tool. The automatic power on\/off feature conserves battery life during intermittent use. The origin set and zero setting functions support fast setup at the point of measurement. This gage is appropriate for both shop-floor use and bench inspection work in light manufacturing and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasuring range: 0 to 8 inches (0 to 200 mm)\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0003 inches with 0.000050-inch resolution\u003c\/li\u003e\n  \u003cli\u003e2.5-inch base with 0.000200-inch base flatness tolerance\u003c\/li\u003e\n  \u003cli\u003eSPC output function for direct data collection\u003c\/li\u003e\n  \u003cli\u003eInch\/mm conversion, origin set, and zero setting functions built in\u003c\/li\u003e\n  \u003cli\u003eSolid rod construction with extension rod included; single SR44 battery included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone electronic depth gage for general precision measurement applications.
