EIT40 Testboard V2

This example shows how to execute the helper function “testboard_evaluation” from the eit_fzj_utils. It is used to plot the results of measurements conducted on the testboard that was built to check the functionality of the eit systems. A theoretical calculated response that is based on the built-in resistors and capicitors is plotted together with the measurement results.

Configs were provided a ndarray
Constructing four-point measurements
Adding column Zg from MD
Adding column Iab from MD
Adding column Ileakage from MD

# The function can be executed with the following command. The first parameter
# has to lead to the datapath of the measurement, the second to the config.dat
# or config array and the third one denotes the output name. Optional
# parameters are the frequency range to compare the measurements to
# (input has to be in log10-space) and the error-percentage of the
# measurements.
