5, 6 DISPLAYS DISPLAYS (3 1/ digits, max. 1999)
· 5 POTENTIAL (mV) / R
EL
(M
Ω Ω
) display:
The upper display shows the recorded
potential in mV (B; C; V modes) or the
electrode resistance in M
W (R mode).
· 6 CURRENT (nA) display: The lower
display shows the membrane current in nA
(X.XX nA, 1.00 is 1.00 nA).
7 CURRENT OUTPUT SENSITIVITY CURRENT OUTPUT SENSITIVITY switch
Seven position rotary switch.
·
This switch sets the sensitivity of the current
output (0.1, 0.2, 0.5, 1, 2, 5, 10 V/nA),
· The position of this switch is monitored at
the
CURRENT SENSITIVITY MONITOR
BNC 35 (1...+7 Volt, 1 Volt / switch
position).
8 CURRENT FILTER CURRENT FILTER switch
(20Hz – 20 kHz, 16 position rotary switch)
· 2 pole or 4-pole tunable Bessel filter (12 or 24
dB/octave) with 16 corner frequencies.
· The following 16 frequencies can be set:
20, 50, 100, 200, 300, 500, 700, 1k, 1.3k, 2k,
3k, 5k, 8k, 10k, 13k, 20k (Hz)
· The position of this switch is monitored at
the
FREQUENCY MONITOR BNC 38
(-8...+7 Volt, 1 Volt / switch position).
9 OSCILLATION SHUTOFF OSCILLATION SHUTOFF unit
Disconnects current injection and capacity
compensation if parasitic oscillations occur.
· A red/green LED shows the state of the
system (red = shut-off triggered).
· THRESHOLD : Sets the threshold for
shutoff activation.
· DISABLE/RESET switch: resets or disables
oscillation shut-off unit.
10 – 12 PENETRATION CELL PENETRATION unit
This unit is used to clean the tip of the electrode
and to facilitate the puncture of the cell
membrane.
· The unit can be operated by a remote switch
connected to the
REMOTE BNC 42
(active LOW).
·
The duration can be set by the DURATION
control 10.
