It uses an LCD display to deliver readings in both inch and metric units, with a resolution of 0.0001 inch (0.0030 mm) and an accuracy of 0.000120 inch. The flat back and straight connection type suit standard indicator holders and magnetic base setups. A carbide contact point provides wear resistance for repeated surface contact. Battery power comes from an included CR2032 cell. This instrument is typically used by machinists, quality technicians, and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 543-342B-10 covers a measurement range of 0 to 0.5000 inch (0 to 12.70 mm) with a measuring force of 1.5 N. It is suited for use on surface plates, mill tables, lathe setups, and CMM fixturing where a drop-style indicator is preferred over a side-reading dial type. The ABS (Absolute) scale function automatically restores the last origin position when the unit is powered on, eliminating the need to re-zero after a battery change or accidental shutdown. Five front-panel buttons with status icons and clear labeling allow straightforward function access during use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eABS (Absolute) scale automatically restores the last origin position on power-up for reliable, repeatable zeroing\u003c\/li\u003e\n  \u003cli\u003eDual-unit readout switchable between inch and metric on the LCD display\u003c\/li\u003e\n  \u003cli\u003eResolution of 0.0001 inch (0.0030 mm) and accuracy of 0.000120 inch\u003c\/li\u003e\n  \u003cli\u003eCarbide contact point for extended wear life under frequent surface contact\u003c\/li\u003e\n  \u003cli\u003eFlat back and straight connection type compatible with standard dovetail clamp holders\u003c\/li\u003e\n  \u003cli\u003eFive-button interface with status icons for easy single-hand operation\u003c\/li\u003e\n  \u003cli\u003eCR2032 battery included; battery-powered with no external power required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style drop indicator compatible with standard dovetail-style indicator holders and magnetic base assemblies used in general metrology and machine shop inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or metrology technicians using a compatible dovetail clamp or stem holder. Ensure the indicator stem is fully seated and the clamp screw is snug before taking measurements. Do not overtighten the clamp on the indicator body, as this can affect spindle movement and measurement accuracy. Handle the contact point and spindle with care to avoid impact damage that would alter calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: LCD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 0.5000 inch (0 to 12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 inch \/ 0.0030 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.000120 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Force\u003c\/strong\u003e: 1.5 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Inch and Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Source\u003c\/strong\u003e: Battery (CR2032, included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 543-342B-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51558056952114,"sku":"543-342B-10","price":593.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/efd21d813d92de05a94001a27f17fad0.jpg?v=1786402119","url":"https:\/\/voomisupply.com\/products\/mitutoyo-543-342b-10-electronic-drop-indicator-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
