2 .4 Required plant situation
Caution:
Make sure that there are no considerable process-relating changes in
your plant during the recurring function test. This means also that the
level in the vessel should not change significantly by filling or emptying
during the test. Make sure that also temperature changes, stirrers,
current reactions in the vessel, etc. can cause level changes.
