Temperature adjustment
(ST / 2K / R / RS models)
This submenu facilitates to adjust the tolerances of the temperature probe in the pH electrode
(zero shift by 0.5 °C at the most).
Notes:
l
Because of the heat capacity of the pH electrode it is neccessary to place it into a water
vessel with at least 2 liters of water.
l
Leave electrode and reference thermometer at least 15 minutes, with temperature
differences between water and electrode > 10°C at least 1 hour in this vessel and stir from
time to time until the adjustment can be made.
Setting: 1 channel instrument
