Abstract��Mechanical blockage fault occurred of an electrical steel sheet (strip) layer resistance measuring instrument for pressure out of control. A pressure plate in measuring plate cannot be pulled out, because the electrode plate and the pressing plate are in the pressing state so that they cannot be uninstalled, and the detection work can not be completed. In order to solve this problem, relevant information and physical control were inspected, its basic structure and work principle were clarified, electrode motor fixing bolt was adjusted, decompression was achieved manually, and then the mechanical jamming was unloaded successfully. After rising electrode plate and a pressure plate, the mechanical blocking problem was successfully relieved. For the later problem that emergence of platen motor can not stop the runaway malfunction and electrode motor condition, the electronic over current protector of the load current setting value was adjusted, the stroke switch positions after processing was repositioned, the fault was eliminated, so that the device was completely back to normal.
