Signal frequencies
Note
Signal frequencies for operation 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. We recommend a frequency of 8.33
Hz for Module 1 and a frequency of 10.00 Hz for Module 2.

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 frequency of the OXYMAT 7 analyzer module.
● If the nominal frequency 8.33 Hz is still set, change the signal frequency to 10 Hz.
