The steel ball-contact tip reaches into the work piece for accurate measurements of turned, milled, and ground parts, and for tool setting gauges, fixtures, and inspections. The continuous clockwise pointer rotation with automatic reversal and helps prevent plus or minus confusion. The ball-bearing lever system with measuring insert swivels through to 210 degrees. The dial has face that can swivel from fully vertical to fully horizontal, and has two dovetail mounts for mounting horizontally or vertically from the top or back. The indicator has a gear-driven, jewelled movement for accuracy. The contact points are frictionally adjustable and replaceable. This dial test indicator meets or exceeds accuracy and performance requirements of national and international standards, and is traceable to the United States National Institutes of Standards and Technology (NIST). Dial readings with three digits, such as 0-10-0, signify that the indicator has a balanced dial. Dial readings with two digits, such as 0-100, indicate that the dial has a continuous dial. Balanced dials are used to read the difference from a specific surface reference point. Continuous dials are used for direct readings and usually have a larger measurement range than balanced dials.
