pH Calibration
The PHS10 pH sensor was calibrated with pH 7.0 and pH 10.0 buffers at the factory before shipping.
Verify the displayed pH agrees with the actual pH. If the pH value deviates by more than 0.2 pH then
adjust the value in the Buffer: #1 pH: Menu by setting the existing pH 7 value to the actual sample value
and then accepting the calibration. For a detailed description see Electrode Standardization in the C‐22
manual.
