Go back into the control room and turn on the Nonin pulse oximeter (Figure 7). Verify that clear
oxygenation & pulse signals are shown on the Nonin Display.

C. Skin Conductance (EDA100C (GSR) module):
Remove the EDA cable from the wall mount inside the magnet room and extend it near the
patient table. Connect the EDA transducer: place the transducer on the tip of two fingers and
tighten the Velcro strap (Figure 8).
To minimize motion artifacts, place the sensor on a hand that will remain mostly still.
Check the tension level. If the strap is too tight, blood flow may be constricted, resulting in a flat
signal. If the strap is too loose, ambient light could enter the sensor, resulting in a noisy
waveform. You can verify that you have a clear signal via the Acknowledge software, see below.

D. ECG Measurement (ECG100C module)
Remove the ECG cable from the wall mount inside the magnet room and extend it near the
patient table. Connect the ECG transducer by plugging in the three colors (see Figure 9) to the
socket end of the cable.
