Note: • To clear a previous calibration and to return to the default value, press Clear at any

time after entering calibration mode. If Clear is invoked during the first calibration

point the instrument returns to the measurement mode.

• The Clear key is displayed only if a previous calibration exists.

pH BUFFER TEMPERATURE DEPENDENCE

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.
