Temperature has an effect on pH. The calibra-
tion buffer solutions are effected by temperature
changes to a lesser degree than normal solu-
tions.
During calibration the meter will automatically
calibrate to the pH value corresponding to the
measured or set temperature.
For manual temperature compensation please
refer to the following chart.

For instance, if the buffer temperature is at
25°C, the display will show pH 4.01 or 7.01 or
10.01.

If the buffer temperature is at 20°C, the display
will show pH 4.00/7.03/10.06.

If the buffer temperature is at 50°C, the display
will show pH 4.06/6.98/9.82.
