Digital-display measuring tool having excessive-deviation alert device

Abstract

A digital display measuring instrument having an out-of-tolerance warning device includes: a digital display measurer, a processor arranged in the digital display measurer, and an out-of-tolerance warning device. The processor is configured to calculate a difference between a measured value of the digital display measurer and a preset reference value, and the out-of-tolerance warning device is configured to receive signals of the processor and output a warning in response to a calculation result of the processor. With the digital display measuring instrument, it is only required to measure the size of the to-be-detected member, and it may be determined whether the size of the to-be-detected member meets a requirement by referring to an output of the out-of-tolerance warning device.
