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 ºC.
