The QB1 is a Go/No-Go gage to demonstrate the quick break function of 3-phase full-wave DC magnetic particle equipment is functional for superior magnetic particle inspection quality. This quick break tester is placed inside the coil (or in line with a cable wrap) during a magnetizing shot, and checks whether the current flowing through a coil is shut off rapidly at the end of a magnetizing shot (this quick shut-off is commonly referred to as Quick Break). Correct quick break function is indicated by illumination of the LED on the tester. Using the QB-1 to check your 3-phase FWDC magnetic particle inspection equipment will help ensure residual field is properly developed during processing and gives sharper resolution of transverse indications. For use with 3-phase full-wave DC equipment only.
