Typical Set-Up Procedure

The Model 3000 comes with an input cable that connects to the DB15 input. One end of

this cable is left open to allow for maximum flexibility in connecting to extracellular

electrodes. The Model 3000 will function properly in this configuration if the head stage

(

) LED is off.

HEAD STAGE

The Head Stage Probe (optional) connects to the DB15 input and will function properly

if the head stage (

extracellular electrodes to the amplifier. The

amplifier should be used as the system ground in the particular recording medium (e.g.

bath or animal ground). Note: Either the Head Stage

front panel must be connected to provide a return current path. If neither ground is

connected the Head Stage Amplifier will saturate and no signal will be measured.

Care should be taken to keep the power cables from all instruments as far away as

possible from the recording setup. One exception is the DC power cable that supplies

power to the model 3000. This side of the cable is DC and therefore does not carry

disrupting power line frequencies. Proper grounding and shielding techniques

should be used to insure a minimum of interference.

Recording

This is a generalized procedure for setting up the AC/DC Differential Amplifier for

recording. Portions of this procedure may need to be modified for your specific

application.
