can be selected.
Cycle time > 5 ms A complete data set containing the following measured values is
always recorded:
■Current pressure at the time of data transfer
■Minimum pressure (min. peak) in the period of the last cycle time
■Maximum pressure (max. peak) in the period of the last cycle time
■Mean value of the pressure over the period of the last cycle time

6.2.2 Automatic update of the drivers
An older driver that was previously installed in the system will not be automatically
updated.
If, during the installation of the instrument, it is detected that there is already a driver that
is suitable, from the operating system's point of view, this driver is automatically used.
If problems occur when using the adapter, first make sure that the current
driver for the adapter is also being used. If necessary, the current driver
must be installed manually, see chapter 6.2.2 “Automatic update of the
drivers”)
6.2.3 Updating or deinstalling the older driver version
In order to update a driver, the “old” driver must first be deinstalled and then the new
driver installed.
