For applications that require measurement accuracy better than our standard ProTable (± .010in inches max. error), we offer our Enhanced Accuracy Option.   This option utilizes custom software in our digital readout to correct for system inaccuracy errors along the entire length of ProTable.  A backfence, is included with the enhanced accuracy option.

With Enhanced Accuracy option, the maximum error of the ProTable measuring system* is  ± .003in inches over the entire measuring range of the ProTable. 

All ProTables are supplied with a calibration chart that compares its measurements to AB grade NIST traceable gage bars. The testing date, operator, and temperature are also recorded on the chart.  For ProTables built with the Enhanced Accuracy Option, values with and without the Enhanced Accuracy option enabled are recorded.  Click image for more details.

For more information about how our enhanced accuracy works, and its benefits, contact us.

The optional wear sheets are also pictured below.

*Note that the error indicated is NOT for the linear encoder, but for the assembled, complete measuring system.  All factors, such as encoder error, straightness, twist, bends, Abbé errors, cosine errors, flatness errors, etc. are taken into consideration and compensated for with this option.
