【 摘 要 】

In this paper the features of controlling of the anode current of the X-ray tubes during their training and testing are described. Requirements for developing of the control and measuring equipment are given. In detail are shown the approaches to the development of two types of microammeters with optical signal transmission: analog, with compensation of the nonlinearity of the transfer characteristics with the use of the optical negative feedback, and digital, in which the values of anodic current are transfered using a microcontroller.
