Isn't there directions on another piece of paper that tells you to only calibrate the OFFSET calibration trimmer (on the front) to display "7.0 pH" and do not adjust the SLOPE calibration trimmer (on the rear) to display "4.0 pH"?

Both of mine came with separate directions for freshwater use. That is why they only send you the 7.0 pH solution.
