The DRO SDS6-2V is a Multifunctional 2 axis digital readout. It can adapt the different needs of machining by modifying the system parameters. It has many graphics machining functions, such as: Arc Calculation function, circular equally dividing holes, drilling hole along an oblique line, Angular Surface Processing, Calculation function, Measurement for Taper Function, Digital Filter Function. These functions bring the easiness for the graphics function. 200 Points Auxiliary Zero Position Function Mid-split Function “mm/inch” Conversion Display Radius/Diameter Switch Display Segmented Error Compensation Linear Error Compensation Power Interruption Memory Sleep Switch Mathematics calculation RS-232-C ineterface (option).
