There is also some confusion about the log/log graph. Again, this graph shows how many cycles until the switches resistance changes by more than a given amount. The graph shows only the data from 0.005 ohms to 500 ohms for the 50,000 cycles. So in the case of the Fluke, even with 5mOhms the switch never changed that much in the 50,000 cycles. This is why it's a flat line. Now the person asking feels there should be a vertical line going up to the 50,000 but because I am not looking for changes less than 5mOhms, we never see this. Basically this was because I didn't care about changes this small. I actually started out just looking at 50mOhms but thought may people would want to see what was happening down in the muck. The Centech and nameless POS meter both reached 20mOhms right from the start.
