AMPLE AS OURCE
Attach a sample inlet line to the SAMPLE inlet fitting.

Use PTFE tubing; minimum O.D ¼".

Sample Gas pressure must equal ambient atmospheric pressure (29.92 in-Hg).

In applications where the sample gas is received from a pressurized manifold, a
vent must be placed on the sample gas line. This vent line must be:

no more than 10 meters long

vented outside the shelter or immediate area surrounding the instrument

ALIBRATION AS OURCES
Attach a gas line from the pressurized source of calibration gas (e.g. a
SPAN GAS
bottle of NISTSRM gas) to the SPAN1 inlet. Use PTFE tubing, minimum
O.D ¼".
(the dual-stage zero Air Scrubber makes zero air)

ENTING
Attach a line to the SPAN2/VENT outlet. It should be:

¼" PTFE tubing

vented outside the enclosure

not less than 2 meters in length
