Youdo not have to change the preset frequency even if you install another analyzer module.NoteCombined operation with ULTRAMAT 7: Signal frequency of the OXYMAT 7If you use an OXYMAT 7 and an ULTRAMAT 7 analyzer module in combined operation, thedefault OXYMAT 7 signal frequency can have a negative influence on the ULTRAMAT 7analyzer 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 10.00 Hz.
