7.4 Replacing the electrodes
The electrode shape is defined by standards and is shown pictographically on the display
before a measurement begins.
Note:
Before each measurement, check that the electrodes used meet the selected standard.
If the wrong electrodes are used, replace them.
1. Open the dust cover.
2. Remove the cover of the test vessel.
3. First, turn one and then the other electrode anticlockwise until they are released from the
thread.
4. Take the other electrode pair that must be used. First, turn one and then the other
electrode clockwise on the thread.
5. Close the cover of the test vessel.
Note: Clean the electrodes when using the electrodes for the first time, or if the electrodes
have been replaced, e.g. if another electrode shape is required for the measurement. Further
