Trouble-shooting instructions

Always start trouble-shooting with the checklist below, if faults occur after start-up or during oper-
ation. This takes you directly (via various queries) to the cause of the problem and the appropriate
remedial measures.

Error messages on display
Errors that occur during commissioning or measuring are displayed immediately.
Error messages consist of a variety of icons. The meanings of these icons are as follows:
– Error type: S = system error, P = process error
$
– Error message type: = fault message, ! = notice message
– S.VELOC RANGE = error designation (e.g. sound velocity outside measuring range)
– 03:00:05 = duration of error occurrence (in hours / minutes /seconds)
– # 491 = error number
"
Caution!
• See the information on Page 47 ff.!
• The measuring system interprets simulations and measured-value suppression as system errors, but displays them as
information messages only.
