This article includes the description of the geometric parameter gage device prototype for synchroton radiation of HERA collider (DESY). The system construction which capable to measure photocurrent, caused by such a radiation in a refractory metal, described here. The system component parts are: measuring heads and photocurrent measuring electronics designed by IHEP, stepper motor by Vacuum Generators with HEDS-550X encoder by Hewlett Packard, PCI-STEP-4CX 4-Axis Closed Loop Step controller by National Instruments. The device is controlled by means of Microsoft Visual Basic programm using Value Motion Windows Libraries. The device prototype was tested in the beam of the DORIS storage ring.
