Electric Potential Simulation and validation do not match

Hi @ all,
i made a simulation of an electric potential in a chamber with a liquid.
Material properties:
liquid:
sigma: 0.114 S/m
epsilon_r: 1.08E+08 (not relevant for electrical potential)
chamber (isolator)
sigma: 10E-12 S/m
epsilon_r: 4
electrodes (Titan)
sigma: 561797.753 S/m
epsilon_r: 1+0.0000033
Physics:
Electric Currents (ec)
with 2 Electric potentials (Ground 0V and the oter 1V)
Study:
Frequency Domain with 20Hz
And the results of the simulation do not match the measured values.
But if i change the electrical conductivity (liquid) to a very very high value of 6000 S/m it match.
What can that be or where is my mistake.
Thanks a lot
Thomas
