9.1 General information
Temperature
measurement with ion
selective measurements
The temperature value is documented with all measurements.
You have the following options to measure the temperature:
 Automatic temperature measurement with
– the temperature sensor integrated in the electrode (NTC 30 or
Pt 1000).
– the integrated temperature sensor of another electrode that is
connected and immersed in the sample at the same time.
– an external temperature sensor (NTC 30 or Pt 1000).
 Manual determination and input of the temperature.
The display of the temperature indicates the active temperature mea-
suring mode:
Operation with burettes Measurements with ISE methods can be automated by controlling
burettes with the meter:
 Connect the burette to the RS232 interface of the ProLab 3000
 If necessary, interlink the burettes
(see also operating manual of the burette).
 Activate the burette control on the ProLab 3000:
Measuring / Burettes settings... / Activate burettes ()
(see section 9.2.3).
 Set the address of the burette on the meter and on the burette
(see page 100 and operating manual of the burette).
Note
Incorrect calibration of ion sensitive electrodes will result in incorrect
measured values. Calibrate regularly before measuring.
