ELECTRODE TEST:
squarewave current source used to test electrode resistance and to adjust the
capacitance compensation. The
switch must be set to
STIM-GATEREC
Recording and reference electrodes should be in a saline solution for resistance
testing.) To accurately measure the impedance, verify at the
the signal is a square wave of 100 Hz, adjust the
square the corners of the waveform. The amplitude of the square wave is a direct
measure of impedance in each of the six ranges (0.1Vp-p/MΩ, 0.2Vp-p/MΩ, 1Vp-
p/MΩ, 2Vp-p/MΩ, 10Vp-p/MΩ, 20Vp-p/MΩ).
This isolated BNC connector enables a stimulus source to be utilized to
STIMULUS:
pass current through the electrode while the unit is in stimulate mode (
center pin of the BNC is the + input and the outer conductor is the - stimulus input.
When the unit is in the (STIM) mode the output will be a measure of the current
passing through the electrode in six ranges (5V/mA, 10V/mA, 50mV/µA, 0.1V/µA,
0.2V/ µA, or 1V/µA).
This toggle switch controls the operating mode for the Model 3000.
