Short Circuit
The amplitude of the sine waves in the MC_Rack data display above alternates in a range of 100 %
and 50 %. Please consider the different levels of amplitudes in direct vicinity side by side regarding
to the contact pads of the 60MEA-SG, but not to the electrode arrangement in the displays.
If there is a shot circuit between neighbor pads of contact pads, all electrodes will show the same
averaged amplitude.
Contact Pads
4.2 Application
A MEA-SG is suitable for many purposes concerning MEA- and MEA2100- and Wireless-Systems that
is why it is very helpful for new users. It is possible to learn about the MEA amplifier and the specific
software Multi Channel Suite or MC_Rack as well as other software programs. Furthermore, you are
able to control the operating mode of the amplifier and you have a tool for troubleshooting.
4.3 Training
A MEA-SG is optimized for training users, because you are able to use the software and work with the
complete MEA-System. AMEA-SG is also a good basis for demonstration.
To learn about the software please read the detailed software manuals. You can try out different features
of the software and their influences on the signal. You can change signal types to make yourself familiar
with specifications and parameter values of the offered sinus waves and spikes. It is the best practice in
software employment, you gain experience and avoid mistakes, which is beneficial for upcoming biological
experiments.
4.4 Demonstration
A MEA-SG is a great tool for demonstrating how MEA-Systems work. In contrast to biological experiments,
you can be sure that the Signal Generator will produce what you want to show, there is no risk of failure,
which is always a problem with living objects.
