Anyone here using the ATK connected to the Apex notice a change in conductivity readings with the ATK 24v turned on or off ?
I have the the 24v power supply for the ATK pump connected to the energy bar (Australian Version). If I turn the power off I get an increase anywhere between .3 to .5 on the salinity reading and vice verse if I turn it off at the outlet. Have tried with just the conductivity probe in a beaker with tank water out of the tank to test for any stray volts and I still get the same issue. I do have a grounding probe in the tank and all cables from the ATK are well clear of the probe cables and not close to each other at all. Anyone have any suggestions ??
