    Most recently, the measurement uncertainty evaluation employs entirely for evaluating the measurement process which is also use to investigate the residual error of length measuring system. This paper presents the measurement uncertainty of the reversal errors that would be compensated by using the error with the measurement uncertainty compensation module. The confident level of measurement uncertainty is approximately 95%. This evaluation result of the measuring system errors were approximately minimized to 8.0 μm.

    Generally, there are many of the error evaluation methods which employed for the length measurement system. The reversal error is one of the important sources of the error. Normally, it is compensated by using the linear error compensation but some residual error is found for measurement uncertainty evaluation. This paper presents a method which is a new design of an automated line scale measuring machine (ALSM) error compensation module. It can be able to compensate the reversal error from the ALSM by reducing the reversal error approximately 10% more.
