FHC microelectrodes are supplied ready to interface directly with the headstage of the FE285 Neuro Amp EX . They are supplied in pairs with male Amphenol connectors, the Active Electrode has a white tag and the Reference Electrode has a blue tag.
Three female Amphenol sockets provide inputs for the Neuro Amp's headstage. The positive and negative terminals are adjacent, while the ground terminal is further away. The positive terminal is distinguished by a slightly recessed surround.
Therefore, the electrode with the white tag should be connected to the positive input and the one with the blue tag should be connected to the negative input. The ground input on the headstage should be connected to a surface electrode with a snap connect lead wire (Not Supplied) and located onto the subject just prior to recording.
The headstage then connects into the five pin input socket on the front panel of the amplifier. Further details can be found in the Bio Amp and Neuro Amp EX User Guide located HERE . Note: These guidelines are for FHC microelectrodes. Other microelectrodes are available and may have slightly different characteristics.
