Attenuation setting
Changing the attenuation setting is also only possible in the TitroLine
operates without attenuation.

The pH or mV signal becomes essentially quieter after a specific setting period when the attenuation is switched
on (low, medium or strong). A minimum waiting period should therefore also be observed for the various
attenuation settings:
