Just make sure the jack where the TRRS plug is plugged into is wired the same. That is, the sleeve connection is ground. If you are plugging in the TRRS plug to a TRS jack, check to make sure the jack sleeve (gnd) contact is connected to the TRRS plug sleeve, as typically, it will be connected to ring2 and not to the sleeve.
Wonder why I am not getting a read out on it then, I know I use to before I re soldered everything, but after soldering I get no reading. Then with those problems started occurring, it seemed responsible from the temp. Which is why I started thinking maybe I have it soldered wrong this time around. Oh well, guess later tonight I will un-hook the controller from the tank, re-attach D48, and hope for the best.
for now, if you need to calibrate ph4, you must load the atlas sketch to calibrate the probe, then load the chauvet sketch again.
wow, guess I will be getting ph 10 fluid then, lol.
