Use the following procedure to setup the instrument:
1.
Connect the zero air supply to the ZERO AIR
bulkhead on the rear
panel (
Figure 2–5
). Ensure that the sample line is not contaminated by
dirty, wet, or incompatible materials. All tubing should be constructed
of PTFE, 316 stainless steel, borosilicate glass, or similar tubing with an
OD of 1/4-inch and a minimum ID of 1/8-inch. The length of the
tubing should be less than 10 feet.
Note
Gas must be delivered to the instrument free of particulates. It may
be necessary to use the PTFE particulate filter as described in “
PTFE
Particulate Filter
” on page

2.
Connect the
EXHAUST bulkhead to a suitable vent. The exhaust line
should be 1/4-inch OD with a minimum ID of 1/8-inch. The length of
the exhaust line should be as short as possible, no more than 10 feet.
Verify that there is no restriction in this line.
3.
Connect a suitable recording device to the rear panel connector. For
detailed information about connecting to the instrument, refer to:

Plug the instrument into an outlet of the appropriate voltage and
frequency.
The 49iQPS is supplied with a three-wire grounding cord. Under no
circumstances should this grounding system be defeated.
