i just got mine today and went to calibrate it, but only had a hole in the back no set screw? so i took the back off to find the adjustment on the board, but my problem was after calibrating it, i put the prob in my tank and it read 11.4 ph "oh no" now i know that's wrong, so i recalibrated and it still read 11.4. so i pulled out the old pinpoint ph monitor calibrated it put it in the tank and read 7.3ph then did a chemical test ya it''s 7.3 ??? now just so you know the prob that came with the milwakee arrived dry so i was thinking this might be a problem, but after reading some info thy say to soak it in a solution to activate it again but it still read 11.4, so just to see were the problem was i swapped the probes and the milwakee prob worked fine on the pinpoint and read 7.2 so i put the pinpoint prob on the milwakee sm122 and it read 7.2, so if any one can tell me what the heck (not what i really said) this kind of thing bugs the hell out of me.

no parts missing, just the set screw on the back is in a hole and i couldn't see it, so i took the back cover off to see instead of just poking around with a screw driver, i don't need to do that next time i calibrate it.
and i just found it funny that the milwakee prob wouldn't work on the milwakee co2 controller but it would work on the pinpoint ph monitor so i am up and running.

A calibration with 1 point isn't a calibration at all, and the manual says to calibrate to 4 and 7.

ya i just found it funny the way it worked out, but i have it up and running so all is good, and i checked it twice just to make sure it is working.
