Click "OK" to start the measurement.
The electrodes are measured one by one and the exact values of the measurements are written
in black letters inside the electrodes, and also in the log file in column "Impedance". The color
code is activated only when comparing with previous measurements or when the check box
“Show Outliers” is enabled. Otherwise the color of the electrodes remains grey.
Click the "Cancel" button to stop a measurement.
Click the "Save" button to save the measurement file in the data base.
Important: You have to actively save a measurement to archive the file in the database!
With the "Export" function, the results of a current or loaded measurement can be exported
in ASCII format. The layout of the ASCII file can be selected in the "Preferences" dialog.
The current measurement can be evaluated or compared to previous measurements of the
same MEA. Evaluation results are shown as color code in the virtual MEA display. An impedance
measurement can either be compared to reference values for a given electrode type, or outliers
in the array can be highlighted, please see above.
The "Compare to" function allows comparing the current measurement with any previous
measurement for that MEA which is present in the database file.
