SS500/SS2000 Analyzer

the previously pulled up position, then tighten slightly with a wrench.
Secure tubing to appropriate structural supports as required.
6. Check all connections for gas leaks. SpectraSensors recommends
using a liquid leak detector.
7. Be sure to vent the bypass return port and pressure relief vent port
(if applicable) in a similar fashion when the unit is in use.
Conditioning the SCS Tubing
Newly installed systems invariably have some trace contaminants and/or are
intended for measuring trace amounts of gas constituents that tend to cling to
system walls, which can result in erroneous readings if the constituents are not
in equilibrium with the system walls. Therefore, once the analyzer and SCS are
completely connected, the entire system (i.e., from the sample source valve to
the vent or return) should be conditioned by flowing sample gas through the
system for up to 12 hours (or until reading stabilizes) after the system is
powered up and before actual readings are taken. Progress of the system
conditioning can be monitored via the gas concentration readings. Once the gas
constituents have reached equilibrium with the system walls, the readings
should stabilize.
Do not exceed 10 PSIG (0.7 barg) in sample cell. Damage to cell
may result.
