5.11 Complex maintenance- and cleaning activities in the measur-
ing unit
For complex maintenance activities or cleaning activities in the measuring unit
we recommend that you dismount the measuring unit and transport it to a clean
laboratory environment.
When the measuring unit is dismounted, its parts are more easily accessible and
the environmental conditions (temperature, cleanliness) are more suitable for
complex maintenance activities or cleaning activities to be carried out.
