Measurement
This module can be read or written. It indicates which measuring-gas point is activated and whether a measuring process is currently
underway. The H2S measurement is displayed here in continuous mode. A measurement starts when a number is written. After a
measuring processis started, the user must write a 0 again in order to prevent repeated measuring. 4 measuring-gas points are
currently supported. A written "one" activates measuring-gas point "one" and starts a measuring process, and so forth. Selecting
another measuring-gas point during an active measuring process has no effect.
