3. Gas pressure subject to
excessive fluctuations.
4. Oxygen senor / detector
not connected.
5. Electrochemical oxygen
sensor is already consumed.
6. IR channel:
Light source not connected
or faulty.
7. Faulty analog
preamplifiering.
8. Contamination of the gas
paths.
3. Check the gas lines preceding and
following the sensor cell.
Eliminate any restrictions found
beyond the gas outlet fitting.
Reduce pumping rate or flow rate.
4. Check connections:
BKS X5 / Oxygen sensor (detector
channel 1)
BKS X6 / detector channel 1 (channel 2)
(see 18.).
5. Exchange sensor (see 25.)

(see 18.)
Light source is cold:
For dual IR channel analyzer
interchange the two light-sources.
Replace the suspect light source
(see 24.2).
7. Check measuring point 17.1.7 or
