Measuring the pH value/Redox voltage

Perform the following preparatory activities when you want
to measure:

1 Press the
surement appears on the display.
2 Connect the electrode to the instrument.
3 Adjust the temperature of the buffer or test solutions
or measure the current temperature if the measure-
ment is made without a temperature probe.
4 Calibrate or check the instrument with the electrode
5 Select the measuring mode by pressing
Note
Incorrect calibration of the pH electrode will result in incor-
rect measured values. Therefore, regularly perform calibra-
tion before measuring.
Measurements can be performed with and without a temper-
ature probe. A connected temperature probe is indicated by
TP on the display.
Note
If you use a pH electrode without a temperature probe, the
instrument is able to use the temperature probe of a conduc-
tivity measuring cell that is also connected to the instrument
and is immersed in the test sample. You have to set up this
as described in section 4.7 C

tivity cell is used.
