Great video upon RET670 testing through Omicron test kit (Diff Characteristic). Here some parameters missing to set in relay test kit viz. Idiff >>, Idiff>. If pick up value less than .3,then you have to set accordingly. Also after drawing curve in characteristics, it is not reflecting same as in test module. Here some video skipped. However it has given good reference for testing. If this clarity is given in upcoming videos, it will really help working engineer like me. Thanks for reading my feedback.
