2. Cut a length of 4-mm tubing long enough to connect the instrument to
the nitrogen exhaust trap bottle.
3. Connect one end of the tubing to the pilot valve port on the instrument’s
rear panel.
4. Connect the free end of the tubing to the pilot valve port on the nitrogen
exhaust trap bottle (see the figure on page B-8).
Caution: To avoid gas leaks, use the sharp knife to cut the PTFE
tubing squarely (that is, perpendicular to its horizontal axis).
