Place the Test-MEA32S12-Lx test model probe inside. Replace the upper unit, and close
the holding clamps carefully.
First Functional Tests
Each MEA amplifier has been thoroughly tested at the factory site before delivery. However,
you may want to perform some tests yourself before you begin your experiment to exclude any
damage that might have occurred during transportation. Some of the tests will also help you to
get to know the basic functions of the hard- and software, like a short tutorial. It will take only
a few minutes time and can save time and trouble in the long run. Multi Channel Systems
recommends running these tests after the setup of your system before you start your real
experiments.
General Performance / Noise Level
Please use the provided test model probe Test-MEA32S12-Lx to test the noise level of the amplifier
immediately after installation. It simulates a MEA with a resistor of 220 k
and a 1 nF capacitor
between bath and electrode. Use MC_Rack, LTP-Director or your custom data acquisition program
to record from the test model probe and to check the amplifier. Please see chapter "Test Model
Probe” in the Appendix.
