Claim Text:
1. A method of measuring the strength of ultrasonic waves for use with an ultrasonic cleaner that applies ultrasonic waves to an object soaked in a cleaning liquid in a cleaning tank and thereby cleans the object, the method comprising steps of: vibrating a particle source soaked in the cleaning liquid with the ultrasonic waves whose strength is going to be measured when the object is not soaked in the cleaning fluid, so that particles are eluted from the particle source into the cleaning liquid; counting a number of particles in the cleaning liquid; and finding the strength of the ultrasonic waves based on the counted number of particles; and wherein the finding step finds the strength of the ultrasonic waves based on the counted number of the eluted particles according to a correlation between the number of the eluted particles and the strength of the ultrasonic waves, the correlation obtained in advance by vibrating with ultrasonic waves the particle source that is soaked into the cleaning liquid and correlating the number of eluted particles separated from the vibrated particle source with strength of the ultrasonic waves.
