Why are you connecting a earth probe to a class 2 which has no ground and when not doing a earth leakage test, only an insulation resistance test?
Poor demonstration, 1) drill switch is double pole so must be locked on, 2) testing to a screw in plastic is pointless, test to say the internal chuck screw.
