The pHs and the temperature dependence of pH buffers are saved
in the pH sensors and are automatically detected during calibra-
tion. It is therefore not necessary to carry out a separate tempera-
ture measurement of the buffer solution.
Refer to the sensor documentation provided by the sensor manu-
facturer for information on technical data, use, servicing and
maintenance.
10.8.2 Calibrating the pH Sensor - Procedure
Proceed as follows to calibrate the pH sensor at the operating
panel:
Procedure
1.
Connect the sensor cable. For details, see the “Before Cultiva-
tion” section and the “Connecting the pH Sensor” sub-section.
2.
Carefully remove the cap with storage solution from the pH
sensor and rins the sensor with distilled water. Do not rub it.
ATTENTION
Wiping or rubbing the pH sensor after rinsing can generate an
electrostatic charge. This can greatly increase the response
time and generate incorrect measured values. At most, lightly
dab the pH sensor after rinsing,
NEVER
wipe or rub.
3.
Call up the calibration menu of the pH parameter and wait for
the short initialisation phase to complete.
After the initialisation phase, the menu display changes:
