Abstract:
1. An ultrasonic measuring gauge comprising: a probe configured to be moved along a surface of a material to be measured, to transmit ultrasonic waves to the material, and to receive ultrasonic waves reflected from the material; an input unit configured to receive a first operation instruction to continuously measure the thickness of the material independent of whether the probe is physically coupled to the material; and a processing unit configured to determine whether the probe is physically coupled or physically decoupled from the material based on the reflected ultrasonic waves received by the probe from the material, when the input unit receives the first operation instruction, operate according to a first mode of operation in which the processing unit is configured to maintain a first continuous measurement session of the material between a first location on the surface of the material and a second location on the surface of the material distant from the first location, regardless of whether the probe becomes physically decoupled from the material between the first and second locations, and determine a corresponding thickness of the material at a plurality of portions of the material along the surface of the material between the first and second locations when the probe is physically coupled to the material at the plurality of portions, based on the reflected waves received by the probe at the plurality of portions, respectively.
