CHANNEL SELECT indicator
LED (XX) indicating the selected CHANNEL for current injection or to be tested for
resistance. The indicator starts at 00, e.g. 02 indicates function at CHANNEL 3 (see also #
2
).
(4)
ELECTRODE RESISTANCE / CURRENT / CURRENT ALL switch
Switch for selecting ELECTRODE RESISTANCE test, CURRENT injection for the selected
channel or CURRENT injection for all channels. The unit of the selected function is indicated
by #
5
.
(5)
RESISTANCE / CURRENT display
Digital display showing the electrode resistance (XX.XX M
, range: 0.01 M
…10 M
) or
the amplitude of the injected current (XXX nA, range: 0…100 nA).
(6)
Current nA / resistance M
LED
LEDs showing that CURRENT injection or ELECTRODE RESISTANCE test is selected.
The amplitude of the injected CURRENT (single electrode or all electrodes) is shown in
display #
5
in nA. The measured ELECTRODE RESISTANCE is shown in display #
5
in M
.
(7)
ACTIVATE push button
Push button for activating current injection or electrode resistance test.
(8)
FREQUENCY potentiometer
10-turn Potentiometer for setting frequency of the current injection pulses
(range: 200 Hz…2 kHz).
Important
: Changing the frequency will also change the amplitude of the current pulse !
(9)
AMPLITUDE potentiometer
10-turn Potentiometer for setting the current amplitude at a selected frequency.
