Manual for Universal Length Instrument (EX-100)

Application
The universal length instrument is applied for absolute and relative measurement. It features in high accuracy due to adopting Abbe comparative theory and a high precision measuring system. It is mainly used in measuring office of factories and various level measuring departments in metal machining industry, specially in machine manufacturing, bearing manufacturing, gauge manufacturing as well as precision tools manufacturing and instrument manufacturing etc industries.

Main subjects to be measured:
1. Shaft, hole, plug gauge, ring gauge, clip gauge, length bar, cone, cylindrical workpiece, lower-grade block gauge, workpiece with parallel planes etc.

2. Pitch diameter of internal thread, thread, thread ring gauge, thread plug gauge

EX-100 instrument is equipped with a data processing system. This system consists of a computer and data processing software, digital display hardware. The measuring results can be output by a printer.

Principal
2.1. The instrument is a contact-type measuring system, using scale as the measuring reference. According to Abbe theory, it is fixed in the center-line of the Abbe measuring shaft and the shaft is rectangle, there is no rotation during movement. The worktable has 5-axis freedom motions, with special accessories such as the inner measuring accessories, the electrical measuring accessories to measure work piece internal/external dimensions. These functions are as same as traditional length instrument.

2.2.2 The digital display system is supported by an EDS100 fine digital display hardware and corresponding software(ED101).
