I have a Milwaukee PH controller (SMS 122) and I do not have the instructions. How do I calibrate it? Do I just put it in the PH7 or PH 10 fluid and adjust?
 
For 50 gold pieces, I will tell you :)

I think most controllers are the same, at least my aquacontroller and pinpoint were. You start with the 7 solution, adjust, rinse probe with RO, place in the 10 solution, adjust, rinse probe, go to 7 again. keep repeating until no adjustments are required.
 
And always let it sit in the particular solution for 20 seconds for the reading to stabilize.
 
Milwaukee recommends using 7.0 calibration fluid only go to the FAQ section of this link for more details.
