(EMG), EEG, EKG, and ERG recordings. The instrument is not intended for clinical measurements using humans. The Model 3000 contains a high-gain, low-noise differential amplifier stage followed by low frequency, high-frequency, and notch filters. Three operating modes are available to accommodate recording, stimulating, and verification of electrode impedance. - Page 5 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. STIM-GATE-REC: The switches allows the user to select Record Mode (...

3000 you will need to complete the following procedure. To set the model 3000 for use with a head stage, all jumpers must be set to the H position (see figure 2 below). Once the jumpers are in the H position the unit can only be used with a head stage. -
Page 9: Operating Instructions
Operating Instructions Typical Set-Up Procedure The Model 3000 comes with an input cable that connects to the DB15 input. One end of this cable is left open to allow for maximum flexibility in connecting to extracellular electrodes. The Model 3000 will function properly in this configuration if the head stage ) LED is off. - Page 10 Ω TEST 3. Turn on power to the Model 3000 and allow it to warm up for 5 minutes. 4. Non Headstage option: connect measuring electrode to the black wire and a reference electrode to the white wire of the probe cable.

Page 12: Theory Of Operation
Theory of Operation Overview The Model 3000 is a high gain differential AC/DC amplifier. The first stage in the amplifier (with either the head stage option or non head stage version) consists of a high input impedance differentially coupled x50 amplifier. The signal from this amplifier is coupled through positive feedback with a capacitor to form capacity compensation. - Page 13 2nA p-p at 100 Hz. The calibrated current source is connected to the electrode leads. 131 Business Park Loop, P.O.
