Many thanks for the replies. I was most concerned about the thermal shock of placing a pre-heated CI skillet on the induction surface, so thanks boilsover for your advice. As to temperatures, Cooks Illustrated suggests placing the CI skillet in an oven until the oven reaches 500F which I'm guessing is not the same as the skillet reaching 500F unless it was left in the oven at that temperature for some time. The reason for oven pre-heating is to ensure that the skillet is evenly heated which is unlikely to occur on most cooktops.
I was attempting to get past the smoke point to season the Matfer carbon steel skillet as that is necessary for the seasoning process in a new pan but I only had limited success because the Miele induction kept cutting out due to overheat protection. My thermoworks infra-red thermometer was showing up to 450F at the centre and as little as 280F at the sides so I only got some seasoning in the centre.
