Legend
The “Legend” describes what you see in the virtual MEA layout: The color coded MEA electrodes
with the value of the measured impedance in black letters in the front, and the electrode names
in white letters in the back.
To evaluate a MEA, you can compare the measured impedances to individual reference values
for each electrode type. Good and bad electrodes will be color coded according to the limits
shown in the legend. It is also possible to highlight outliers. You can change the default limits
in the “Preferences” dialog.
Alternatively, the user can compare the current measurement to any previous measurement
from the same MEA present in the database file. Use the tick boxes or the drop down menu to
select the reference measurement. The date of the reference measurement will appear in the
upper right corner of the legend.
Status Line
The status line will indicate the actual status of the software and suggest a next step, respectively.
