Answer:
The brachial artery is located on the inside of the arm between the bicep and tricep against the humerus bone. Place your two fingers on the artery to check for a pulse, just as you would for other victims.
It's more accurate, especially since heart rate is almost universally measures in beats-per-minute, than, say, timing your pulse for a [factor of 60] seconds (30 seconds, 20 seconds, 15 seconds, 12 seconds, etc.).
