Click the "Help" button of the header for using the online help.
Click the "Info" button of the header.
The "About MEA-IT" dialog shows the serial number of the MEA-IT device and the actual
MEA-IT software and firmware version.
MEA Identification Line
The MEA Identification line shows the “Layout” and the individual "MEA-ID", usually
the serial number engraved on the back side of each MEA. These parameters can be
entered in the "Select MEA" dialog at the beginning of each measurement (please see below).
The "Time of Initial Operation" is a date that should be entered at the first measurement
of each MEA. It will be saved with the MEAs database file and helps the user to keep track
on the age of an array. A "Comment" can be added at any time before and during the
measurement. The comment will also be saved in the measurement file.
Virtual MEA Layout
The virtual MEA layout shows the MEA electrodes in grey color, labeled with their electrode
name in the layout grid, selected in the "Select MEA" dialog (please see below). The numbering
of the MEA electrodes in the display corresponds with the layout described in the MEA datasheet.
Measured impedance values are shown in black letters on each electrode.
