A method for temperature compensation of a test tone used in meter verification is provided. The method uses a drive amplifier to provide a drive signal to a drive circuit, wherein the drive circuit includes a drive mechanism in a meter assembly of a vibratory meter. The method measures a first maximum amplitude of the drive signal at a first temperature of the drive circuit, and measures a second maximum amplitude of the drive signal at a second temperature of the drive circuit. The method also determines a maximum amplitude-to-temperature relationship for the drive circuit based on the first maximum amplitude at the first temperature and the second maximum amplitude at the second temperature.
