5.1

Preparing the device for the measurement

NOTE!
The device is preconfigured per default for measuring the pH value.
NOTE!
When measuring, always ensure that your pH and redox combination
electrode is in good condition and was cleaned and dried before being
inserted into the solution.

Measuring the pH value

Selecting the measurand
Definition
Connect the combination electrode and, if applicable, the temperature probe
to the device.
Briefly press the
If a zero point correction (offset) or slope correction has been performed on
the voltage or temperature measurement (see chapter 7.1, page 32), the
device accordingly briefly displays "
The device is subsequently ready to commence measuring.
The device is preconfigured per default for measuring the pH value.
If the device has been configured for a different measurand in a user-
defined operation, first select the measurand "pH" (see "Parameter "InP":
selection of a measurand", page 35).
The pH value describes the acidity or alkalinity of an aqueous solution.
pH values under 7 indicate acidity, pH values over 7 indicate alkalinity,
pH 7 = neutral.
