29 GROUND GROUND plug
This connector is linked to the internal system
ground, which has no connection to the 19"
cabinet and the mains ground to avoid ground
loops. Ground connectors are also on the rear
panel (see REAR PANEL ELEMENTS,
GND/EARTH connectors).
30-32 VC COMMAND INPUT VC COMMAND INPUT BNC connectors
(see also CUR.STIMULUS INPUT 40/41)
The command signal for the voltage clamp mode
(V mode) is a sum of following input signals:
· 19 HOLDING POTENTIAL (mV), with a
+/0/- switch for selecting the polarity
· 32 analog input BNC (/10mV = 10 mV/mV),
· 30 analog input BNC (/40mV = 40 mV/mV).
· Each input BNC is equipped with an on/off
toggle switch that can be used to ground
unused inputs to avoid noise pickup.
34 POTENTIAL OUTPUT (x10mV)
POTENTIAL OUTPUT BNC connector
BNC connector monitoring the recorded
potential with a gain of ten.
35 CURR.SENSITIVITY MONITOR CURRENT SENSITIVITY MONITOR
This BNC connector provides eight output
voltages (0-7V, 1 Volt per switch position)
corresponding to the eight positions of the
CURRENT OUTPUT SENSITIVITY switch.

36 SWITCHING FREQUENCY
SWITCHING FREQUENCY (kHz) display
The selected switching frequency (see 17 ) is
displayed with a 3 digit display. In the linear
modes (B and R modes) it must show zero.
37 CURRENT OUTPUT
CURRENT OUTPUT BNC connector
BNC connector on the front panel, monitoring
the effective (average) current passed through the
electrode.
38 FREQUENCY MONITOR FREQUENCY MONITOR BNC connector
The position of the CURR. FILTER switch 8 is
monitored at the FREQUENCY MONITOR
BNC (-8...+7 Volt, 1 Volt / switch position).
40 / 41 CURRENT STIMULUS INPUT
CURRENT STIMULUS INPUT
The current injected through the electrode in the
current clamp modes (B and C modes) is the
sum of the following input signals:
