Note
Signal frequencies with two OXYMAT 7 analyzer modules
If you install a second OXYMAT 7 analyzer module, the operating and signal frequencies of the
two OXYMAT 7 analyzer modules have to differ from each other.
• Check the set frequencies of both OXYMAT 7 analyzer modules.
• If necessary, adjust the frequencies of the modules again. We recommend:
– A frequency of 8.33 Hz for Module 1
– A frequency of 10.00 Hz for Module 2.

• Table References 1 - Operating Manuals LUI (Page 135)
• Table References 2 - Operating Manuals PDM (Page 135)
Note
Combined operation with ULTRAMAT 7: Signal frequency of the OXYMAT 7
If you use an OXYMAT 7 and an ULTRAMAT 7 analyzer module in combined operation, the default
OXYMAT 7 signal frequency can have a negative influence on the ULTRAMAT 7 analyzer module.
• Check the set signal frequency of the OXYMAT 7 analyzer module.
• If the nominal frequency 8.33 Hz is still set, change the signal frequency to 10 Hz.
You can find additional information in the bibliography in:

Note
Flow-type reference path ULTRAMAT 7
When you flush the reference chamber, make sure that it is supplied with gas. Otherwise, the
error message "Intensity outside tolerance" may occur. If the error continues, take the following
measures:
• Check the IR source. Replace it if necessary.
• Clean the cuvette.
Note
OXYMAT 7 pressure correction
The OXYMAT 7 analyzer modules have an internal pressure sensor for correcting the effect of
pressure on the measured value.
In the case of OXYMAT 7 the pressure sensor is connected with the sample gas path and
therefore always measures the current sample gas pressure.
