STEP 1 : Make all the Correct Connections.
1. Connect Left Leg Electrode (LL) of human to the positive point (LL) of op-amp circuit.
2. Connect (avg) point of right arm electrode and left arm electrode of human to the negative point (avg) of op-amp circuit.
3. Connect Right Leg Electrode (RL) of human to the ground point (RL) of op-amp circuit.
STEP 2 : Click on check button to check for Correct Connections.
STEP 3 : If Connections are not correct click on reset button for reset connections.
STEP 4 : If Connections are correct click on play/pause button to see waveform for lead aVF.
STEP 5 : Click on waveform tab for data calculations and BPM measurement .
STEP 6 : Click on print button to save the observations.
