1-point pH calibration
1-point calibration can be carried out with the pH 7 buffer solution provided. Alternatively, pool water can be used if its pH value can be measured
precisely (e.g. using a photometer) and is in the area of pH 7.
Never use buffer solution which is more than 12 months old.

Target measurement
Allows you to enter the actual pH value. Enter pH 7.0 here if you are
performing calibration with the pH 7 buffer solution.
If you are using pool water for calibration, please enter the pH value you
measured.
After correct entry, confirm the calibration with
If you notice significant discrepancies between the current measurement
and the value measured by you (e.g. using a photometer), you should
carry out a 2-point calibration.
