PROBLEM TO BE SOLVED: To obtain an accurate measurement value by detecting contact speed and acceleration when a probe touches an object to be measured and generates warning when the measured values are outside a tolerance for prompting remeasurement. SOLUTION: The parts of a probe 17 and a Z-axis arm 16 are gripped and the probe 17 is moved by manual operation, the tip ball of the probe 17 is brought into contact with each part of a work 19 and each part of the work is measured. In this case, the probe 17 is moved to precisely measure the axes of X, Y, and Z coordinate, and the deviation between X, Y, Z display values being displayed by a host system 2 and display values being measured precisely is calibrated. Then, by bringing the probe into contact with the specific surface of the object to be measured for several times by changing contact speed and acceleration, the tolerance table of the contact speed and acceleration is created from the measurement values. Then, the contact speed and acceleration when the probe 17 touches the object to be measured are detected, thus generating warning and prompting remeasurement when the detected values are out of a tolerance.
