Measuring the ISE concentration
Preparatory
activities
Perform the following preparatory activities when you want
to measure the concentration using an ion sensitive elec-
trode:
Note
Incorrect calibration of the ion sensitive electrode will result
in incorrect measured values. Therefore, regularly perform
calibration before measuring.
Temperature probe
Measurements can be performed with and without a temper-
ature probe. A connected temperature probe is indicated by
TP on the display.
Note
The meter automatically recognizes the type of the temper-
ature probe used. As a result, you can connect electrodes
with the NTC30 or Pt1000.
The temperature measurement is absolutely essential for a
reproducible measurement. If the measurement is made
without a temperature probe, proceed as follows:
Note
It is not possible to enter temperature values manually for
ISE measurements and calibration.
1 Connect the electrode to the instrument.
2 Adjust the temperature of the test solutions or mea-
sure the current temperature if the measurement is
made without a temperature probe.
3 Select the ISE measuring mode by pressing
m
.
4 Calibrate or check the instrument with the electrode.
1 Measure the current temperature.
2 Temper the test sample and the calibration standards
to the same temperature (in the range
± 2 °C)
