We present the quality control tests performed on a monophasic X-ray equipment and on two noninvasive monitoring systems. The results were compared with the values obtained using an invasive monitoring system and a hyperpure germanium detector, providing correction factors for utilization of the noninvasive voltage meters in the quality control program of X-ray equipment. We concluded that there is a need for periodic calibration and control.
