3.2.5.1 Display of counter increment (flow value)
The entries of the measurement period archive can be called into the display. Here the
increments of the counters in comparison to the corresponding previous entry are also
included. They are identified with a "
D
". Normally, with a counter increment the flow
(consumption) within a measurement period is involved.
This is not the case when an archive row has been entered due to a special event (e.g.
setting of the clock or of a counter, appearance of an important status message). Then the
segment "
D
" and the abbreviated designation flash for the displayed counter increment in
order to make the user aware of this special feature.
With an error within an archive row (detected by the CRC procedure) the complete flow
value flashes. If for some reason no consumption can be determined, an appropriate error
message is issued. In both of the latter cases the displayed value may not be used for
billing purposes.
3.2.5.2 Calling up archive entries
Since the measurement period archive may have up to 11500 entries, an entry that is to
be checked cannot be reasonably accessed with the cursor keys. The check is made
easier using a "skip function" with the entry of the desired destination address in the
following columns:
·
Block number
·
Date and time
·
Counter reading
The entry takes place initially by selecting the desired column (block number, date/time or
counter reading) in any row. Then the "ENTER" key is pressed to enable entry of the
desired value. Then by terminating again with "ENTER" skipping takes place to the desired
value or to the nearest possible value. If the desired value is not present at all, skipping
occurs to the "nearest" value. If you are located in a "wrong" column in which the skip
function is not possible, the message "8" is output.
