4.1 Mounting the MEA
Open the upper part of the device by moving the triangular edges of the lid outwards. The lid
swings open. Before inserting the MEA note its layout and the individual serial number. Please
see chapter "Compatible Microelectrode Arrays". Insert the MEA carefully into the provided area
in the middle. Make sure that the MEA is correct orientated. Close the device by pressing down
the lid and moving the triangular edges of the lid inwards.
Positioning the MEA
Important: MEAs are not symmetrical! Therefore, the small writing (for example NMI, LEITER,
MEA type) on the MEA chip should be on the right side viewed from the front of the MEA-IT
device. MEAs with one big internal reference electrode should be placed with reference
electrode to the left side in the MEA-IT device. Otherwise, the MEA layout will not match
with the pin layout of the MEA-IT device.
When placing a special MEA into the amplifier, for example HighDense MEA, 4Q1000 MEA
or HexaMEA, please make sure that the orientation of the MEA is correct, respectively.
