Usually, these machines are measuring conductivity which is absolutely the opposite of resistivity. A lot of customers are running 5-10 megaohms. When you get down to the 2-5 conductivity micro siemens, they are basically staying down low. The lower you go on conductivity, the rinse cycles if it is running an automatic cycle. I would recommend running between 5 and 10 micro siemens, the conductivity in the batch machine.
