SS1000 Operator’s Manual A–1
Appendix A: Troubleshooting
This section presents recommendations and solutions to common problems,
such as gas leaks, contamination, excessive sampling gas temperatures and
pressures, and electrical noise. If your analyzer does not appear to be
hampered by one of these related problems, contact your sales representative
for service.
Gas Leaks
Probably the most common cause of erroneous measurements is outside air
leaking into the sample supply line. It is recommended the supply lines be
periodically leak-tested, especially if the
analyzer has been relocated or has
been replaced or returned to the factory for service and the sample lines have
been reconnected.
Membrane Separator Filter
The analyzer comes equipped with a membrane separator filter that separates
out entrained liquids from the sample gas. If moisture accumulation is
suspected, briefly open the bypass valve on the membrane separator filter to
clear out any liquids.
If measured moisture concentration levels are higher than actual or an excess
amount of wet ga
s has pass
ed through the filter, the membrane may need to
be replaced.
To replace the membrane:
1. Detach the 1/8" inlet tubing and the 1/4" compression fitting from
the sample supply port on the analyzer.
2. Unscrew the two 10-32 socket head cap screws that attach the filter
to the analyzer.
Do not use plastic tubing of any kind for sample lines. Plastic
tubing is permeable to moisture and other substances which can
contaminate the sample stream. SpectraSensors recommends
using 1/4" O.D x0.035" wall thic
kness, seamless
stainless steel
tubing.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
