Burkert Type 8136 - Manual (Page 50)

Maintenance: Due to external influences, the instrument function is
limited. The measurement is affected, but the measured value is still
valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
The following table shows the error codes in the status message
"F
ailure" and gives information on the reason and rectification. Keep in
mind that some information is only valid with four-wire instruments.
