(18) SERIES RESISTANCE COMP. (%) potentiometer
Potentiometer for setting the compensation for the SERIES RESISTANCE (VC
mode) in percent of the resistance value that is set at the BRIDGE BALANCE
potentiometer 12. Therefore, it is important to set the BRIDGE BALANCE
correctly before using the series resistance compensation (see also 40 and 41).
Very Important: When using the SERIES RESISTANCE compensation do not use the
potential values recorded from the POTENTIAL OUTPUT (mV) BNC connector (27) or the
value shown at the POTENTIAL display (39) as a measure for the membrane potential, since
these values include also the additional voltage generated by SERIES RESISTANCE COMP.
for compensation of the voltage drop at the SERIES RESISTANCE.
For instance, when for calculating I/V curves do not use the potential values recorded from
the POTENTIAL OUTPUT (mV) BNC connector (27). Use the COMMAND potential
instead.
COMMAND set unit
The COMMAND set unit consist of (19) GATE / HOLD switch, (20) +/0/-
switch and (21) POTENTIAL (mV) potentiometer
(19) GATE / HOLD switch
Switch that determines the function of the POTENTIAL (mV) potentiometer 21
(see also 21).
(20) +/0/- switch
Switch for setting the polarity of the holding potential or gated potential stimulus in
VC mode, respectively (see also 21). In zero position the holding potential or gated
potential stimulus is disabled.
(21) POTENTIAL (mV) potentiometer
Ten-turn potentiometer for generating a holding potential (switch 19 in HOLD
position) or a gated stimulus (switch 19 in GATE position) in VC or VCx10
mode; range: 1 V (100 = 100 mV) or 10 V (100 = 1 V), respectively. Polarity
is set by the switch 20.
OSCILLATION SHUT OFF unit
The OSCILLATION SHUT OFF unit consist of (22) THRESHOLD potentiometer,
(23) DISABLED / RESET switch and of (35) OSCILLATION SHUT OFF LED.
