Capacitive electrodes EK with signal conditioning instrument 29
Set-up
4.3 Continuous level measurement
When you state the medium with your order, the oscillator of the electrode is already pread-
justed. In this case the medium is stated on the order confirmation.
• Choose with the changeover switch on the oscillator the stage according to the following
schedule.
Take the column corresponding to your medium and choose by means of the length of your
electrode the suitable range.
The stated lengths partly do not correspond to the actually available electrodes.
When the medium has a DK-value which is between the values stated in the table, the max.
permissible electrode length per measuring range must be averaged appropriately.
In case of larger lengths or when there is nothing else stated in the table, choose range 3.
If you are not sure, set the changeover switch always to the next higher stage.
