RKE PH probe calibration

How are you supposed to calibrate, check calibration? I have the 10 and 7 fluids and know where the calibration mode is. I place the probe in the respective fluid but it does not "match" the fluid #, I let the raw data stabilize and read the sensor output. They do not match IE: 10 fluid shows 9.38 and the 7 shows 6.48. Am I supposed to adjust the "target until they read the same and call it good? Or is there something else I need to do? (yes I rinse the probe before moving to other calibration fluid)
