B. OPERATION
ELECTRODE
The ELECTRODE control switches provide a unique
combination of microelectrode terminations~ A push of
the button changes the 2400 system from (1) a high
current stain generator for marking recording sites to a,
(2) controlled positive or negative ideal current source
up to 1000nA to (3) a low noise neutralized preamplifier
to your microelectrode for any future need that you
may encounter. All this without ever touching the
probe or the microelectrode.
STAIN
Your microelectrode recording site can be marked for
easy visual identification by using either the STAIN
switch or the controlled but smaller currents from the
CURRENT PUMP. The STAIN generator provides a high
level resistive limited current with polarity selections
for use with both metal and glass electrodes.
The 2400 also provides for any future stain requirements you may
have by giving you direct access to the electrode via the EXTERNAL
BNC CONNECTOR.
