If you are using pressure compensa�on, check that the
pressure transducer is switched on (see Sec�on 7.2.2).
Ensure there ar
e no leaks in the pipework.
Analyser measurements are unstable.
Check that the sample gas supply pressure is correct: see
Sec�on 2.4
.
Check that the analyser is not being subjected to high
levels of vibra�on and ensure there are no leaks.
Check that the sample gas inlet is not blocked, and that
the sample gas supply to the analyser is not restricted.
Ensure there are no leaks in the pipework.
The
analyser will not calibrate.
Check that the correct low and high calibra�on gases are
