Impermissi-
ble electronics
temperature
– Temperature of the elec-
tronics in the non-specified
section
– Check ambient temperature
– Isolate electronics
– Use instrument with higher
temperature range
S601
Overfilling
– Danger of vessel overfilling
– Make sure that there is no
further filling
– Check level in the vessel
