4.1 General adjustment
When you state with the order already the
measured product, the electrode will be
adjusted appropriately. The dielectric constant
value and the conductivity of the product as
well as the electrode length are considered.
The figures in brackets relate to the figure
under chapter “3 Electrical connection“. During
set-up the electrode must be adjusted with the
original medium.
For adjustment of the electrode you have to
open the housing cover. On the oscillator you
can choose with the changeover switch (13)
the sensitivity range of the electrode.
E14, E15 E17, E18
Step I 0…25 pF 0…120 pF
(sensitive)
Step II (standard) 0…100 pF 0…600 pF
Step III (less
sensitive)
0…400 pF 0…3000 pF
The instruction for adjustment or switch point
adjustment is stated in the operating instruction
of the appropriate signal conditioning
instrument.
