Title:
THRESHOLD CHANGING METHOD AND INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/193705
Kind Code:
A1
Abstract:
Provided are a threshold changing method and inspection device that make it possible to change a threshold to be used for inspection according to the flow rate of air supplied from an air source and a received threshold. This changing method comprises: an original flow rate measurement step for measuring an original flow rate supplied to an inspection device from an air source; a threshold reception step for receiving a threshold associated with the original flow rate; a ratio calculation step for, in the equation threshold Yth = (coefficient A1 × original flow rate X + constant B1) × ratio C, substituting the value of the threshold received in the threshold reception step for threshold Yth and substituting the value of the original flow rate measured in the original flow rate measurement step for original flow rate X, and thereby calculating the ratio after changing to the threshold received in the threshold reception step; and a threshold changing step for changing the value of the ratio C in the equation to the ratio value calculated in the ratio calculation step and using the changed equation to change the threshold.
