The temperature has an effect on pH. The calibration buffer solutions are affected by temperature

changes to a lesser degree than normal solutions. During calibration the instrument will

automatically calibrate to the pH value corresponding to the measured or set temperature.

During calibration the instrument will display the pH buffer value at 25 °C.
