Again we start with no mains (220 V) being supplied (using a variac transformer) which is adjusted at about 220 V ac supply. (Please be aware that I notice "within the red circle 'b' whereas it should be, within circle 'a', instead! The 'thermo-relay' delays about 8 à 10 seconds. The two meters being not operated at similar sensitivities. The left one being operated via the 1:10 voltage divider (x10)!
