	Magnetic poles of superconducting wigglers (SCWs) are passed through "training" phase during fabrication of SCWs at Budker INP. In "training" procedure magnetic field is increased until superconducting coils enter the resistive state. Quench Recording System (QRS) is used for registration of waveforms in each coils to determine fault initiator coil. The total number monitored coils reach 312. Outdated QRS is based on modules in CAMAC standard and requires modernization. The basis of the new system is VME64-BINP crate with multichannel digitizer ADCx32 and RIO-module for safe signal receiving in high-voltage common-mode environment. The structure and details of the new system, as well as the experience of using the old one are given in the report.
