QC
I am running Fisher's PH 4, 7 and 10 and getting a negative number as the result, am I missing something? is there a calculation? What QC are you doing. I can't find it in the manual. Is the calibration they are talking about, the QC?

What is the model and serial number of the pH electrode attached to the T50? What is the slope and offset values after you perform a calibration? Wgat results are negative? The slope is always a negative result due to the Nernst Equation. Please provide a printout of the method and the example of the calibration to uslabtechsupport@mt.com to review.
