Procedure for the 1-point pH calibration:
Dip the pH electrode in a buffer solution of pH 7.
Wait until Current Value pH stabilises and remains constant.
Under Cal. Value, enter 7.00 and confirm with "OK".
Touch Next to start the calibration.
The page that now appears shows the Electrode Slope and Offset parameters (zero shift). Although it is possible to adjust these
values here, they do not need to be changed.
Touch Ready to complete the calibration.
Alternatively, proceed as follows:
Take a water sample from the pool and determine its pH value using a photometer. The measured value should lie around pH 7 to
ensure that calibration will be correct.
Dip the electrode into the measured sample. Wait until Current Value pH stabilises and remains constant.
Under Cal. Value, enter the measured value and confirm with "OK".
Touch Next to start the calibration.
The page that now appears shows the Electrode Slope and Offset parameters (zero shift). Although it is possible to adjust these
values here, they do not need to be changed.
Touch Ready to complete the calibration.
