Greeting fellow hobbyists,
I have the PM2 w/ conductivity probe hooked up into my sump. I only have a single temp probe (hooked up to PM1) right next to it in the probe holder with the pH probe. I had finished calibrating the conductivity probe in the 53,000/uS solution, after which I went into the fusion dashboard and the conductivity reading says 25 ppm (while still in the calibration solution?) How's this possible? Shouldn't it read 35?
Thanks in advance
