    4.1.2 Leak-Check Procedure A leak check prior to the sampling run is optional but strongly recommended; a leak check after the sampling run is mandatory. The leak-check procedure is as follows: Temporarily attach a suitable (e.g., 0- to 40-cc/min) rotameter to the outlet of the dry gas meter, and place a vacuum gauge at or near the probe inlet.
