Diagnostics Comparison Log
1
The Diagnostics Comparison Log provides a comparison between current diagnostic val-
ues (current fingerprint) and those of a reference time (reference fingerprint, for example,
at time of commissioning). Since the diagnostic values (dataset type "Diagnostic Values",
) are velocity-dependent, it is necessary to use a velocity-adaptive comparison.
Five gas velocity range classes are calculated from the velocity range of the meter. The cur-
rent diagnosis values are stored in Current Classes 1 to 5, while the reference values are
stored in Reference Classes 1 to 5.
Reference values are collected after the meter has been commissioned or after the
classes have been cleared. Reference values are stored in the Reference Classes 1 to 5. If
a Reference Class is filled with an entry, the next valid entry is stored into the same velocity
range but in the corresponding Current Class (e.g. if Reference Class is filled, the next
value from within this velocity range will be stored in Current Class 1). During operation,
the Current Classes are continually overwritten with new entries. The Reference Classes
stay unchanged until they are manually cleared.
Per default the Diagnostics Comparison Log operates bidirectional, saving separate data
for both flow directions. The values are stored in the gas velocity classes 1 to 5, depending
on the gas velocity.
