Ken, Without stirring there is a noticeable difference in the shutoff point which can be controlled by electrode spacing. But with stirring it is much less pronounced. The reason is that the ions are more evenly distributed when stirred. The conductivity gradient in unstirred is very high between the electrodes. In this case a small difference in spacing can be easily noticed by the shutoff circuitry. However in that case the PWT reading will also drop considerably further after shutoff.
In a stirred unit electrode spacing has much wider tolerance because the ions are being spread out in the water and it takes much longer to get the same amount of conductivity between the electrodes. With our table top stirring units one can increase the PPM by spreading or reduce it by closing the spacing but it is a very broad adjustment. Not critical at all.
