3. Turn the 3-way program switch on the front panel of ECG amplifier to GND .
Turn on the amplifier. A signal of zero (0) volts is sent by the amplifier to the
data recorder. If necessary, set the baseline of the recording channel to zero (0)
using the controls of the data recording system.
4. Check the calibration of the recording channel. Turn the 3-way program
switch to
1mV
. The signal on the recording channel should show a deflection
of 1mVDC, which is the nominal voltage used to calibrate ECG amplifiers. If
needed, use the unit conversion function of the data recording program to
make the 1mVDC signal from the ECG amplifier create a 1mv deflection on the
recording channel.
5. After the calibration check, turn the 3-way program switch to MEAS . Depending
on the sets of leads and electrodes that have been attached to the animal or
heart, ECG or biopotential signals should appear on the output device.
