1. Attach the provided silver wire or pellet to the amplifier's ground and place it into the bath,
near the rim of the culture chamber. If you use a MEA with internal reference electrode,
connect the ground to the reference electrode socket (pin 15) with the provided connector.
Make sure that the orientation of the MEA inside the amplifier is appropriate.
2. Replace the shielding. Make sure the setup is complete.
3. Click Change MEA again to reconnect the electrodes to the amplifier's input stage.
4. Wait until the amplifier has recovered and you see the standard noise level on all channels
before starting your experiment. The recovery time depends on the electrodes used and
usually takes about 1 or 2 minutes.
5.4 Grounding Defective Electrodes
You can ground defective electrodes with the MEA_Select program. In the following example,
electrodes No. 15, 16, 24, 25, 26, 35, and 47 show a very high noise level.
