Setup Procedure
2-6 49iQ Instruction Manual Thermo Scientific
Use the following procedure to setup the instrument:
1. Connect the sample line to the SAMPLE 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 9-17 . ▲
Note Gas must be delivered to the instrument at atmospheric pressure. It
may be necessary to use an atmospheric bypass plumbing arrangement as
shown in
Figure 2–6 if gas pressure is greater than atmospheric pressure. ▲
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 less 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:
“ Connecting External Devices ” on page 9-1
Communications > “ Analog I/O ” on page 3-89 and “ Digital I/O ”
on page 3-90 .
4. Plug the instrument into an outlet of the appropriate voltage and
frequency.
The 49iQ is supplied with a three-wire grounding cord. Under no
circumstances should this grounding system be defeated.
