L-34LMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.Easy operation, compact and lightweight, designed for use on the shop-oor right beside the production line.•D.A.T. (Digimatic Adjustment Table) function aids adjustments such as centering and leveling, and substantially reduces the time required for preliminary setup operations.What is the D.A.T. (Digimatic Adjustment Table) function? •Icons on the built-in operation panel in the main unit allows easy operation for anyone.•Compact, lightweight design from incorporating electronic components inside the main unit.•Icons representing geometric tolerances, such as roundness and coaxiality, are used. The measurement can be started just by pressing the desired icon and then the start button.Dedicated analysis unit type (RA-120)•Compact, lightweight design is realized by incorporating electronic components inside the main unit.•Provides functions comparable to upper grade models, such as a Z axis equipped with digital scales, a wide range detector, and continuous inside/outside diameter measurement.•ROUNDPAK, a data analysis program employs Windows OS and archived higher level of analysis.Data analysis by PC (RA-120P)Feed the digital micrometerhead of the trntable bythe deviation displayed.PreliminarymeasurementDisplay of misalignmentsSimple adjustmentCentering/leveling completeCentering range: ±3 mmLeveling range: ±1° Preliminary measurement oftwo cross-sections ’A’ and ‘B’.Initial misalignmentof centers atturntable surface Initial misalignment of axes Turntable axisTurntable axis WorkpieceWorkpieceRoundtest RA-120/120PSERIES 211 — Roundness Measuring InstrumentsRA-120PThe analysis capabilities for the various models (RA-120/120P/10) vary.
