Using the same measurement methods as ordinary
calipers, data can be sent to a device by pressing thedata transmission button.
A large display and backlight are used to make it easierto read measured values and a fixed value mode isequipped, which records values held for 0.5 seconds orlonger during measurement.（Figure4）3-3）Three measuring points

awareness of safe plant operation has increased in recent
years, plant owners have been requesting contractors to
perform gap measurements, and contractors have been
adopting this method to differentiate themselves fromtheir competitors.
However, the current measurement methods often use
ordinary calipers and taper gauges, and there areproblems such as reading error of measured value,erroneous recording, and troublesome report
preparation.
