Check the pulses at the points shown.
In the check boxes below, click on box if the pulse is present. Do it for all the five pulses. You can ignore the Fire pulse on the right wrist.
Now click the "Analyze" button. Wait for the result of analysis. A picture will also appear below the Analyze button. It will show you at what point on your left hand finger, you should touch.
Just a light touch for about 10 seconds should do. If you are sensitive enough, you might even feel a little throbbing at that point. The patient might feel a little drowsy also.
