2.2 Displaying archives on the EK280
i
A comprehensive description of the archive can be found in chapter 8.3.3)
To display the contents of an archive, move the cursor to the archive header and press the ENTER or key.
The Archive Headers are located on the Admin. and Serv. tabs under Archives, the log books also are under
Status.

EK280 Application Manual 11
The archive data is displayed in table format, i.e. in columns with headings. Individual columns are separated
by one or more spaces. The column header contains the name of the value displayed in the column and
where applicable the unit. Space permitting, multiple columns are displayed simultaneously.
The and keys move the cursor through the neighboring columns, the cursor remains at the left column
edge and the columns are moved along in the display. The and keys move the cursor to older or newer
entries (rows).
Archive view function keys in detail:
Move right one column. (The columns will be moved to the left by one column.)
After the last column the cursor returns to the first column.
Move left one column. (The columns will be moved to the right by one column.)
After the first column the cursor moves to the last column.
Move down one row. The first row then appears again after the last one.
Move up one row. The last row appears after the first one.
ENTER Input for the search function in the archive.
(chapter 2.2.2 Search function for checking archive entries, p. 12)
The function is executed on the left-hand column.
ESC Exits the archive and returns to the archive header.
+ Go to the archive entry point, i.e. the value at the top left of the table.
+ The LIS-address and the OBIS-Code of the value will be displayed.
The function is executed on the left-hand column.
2.2.1 Progress index
The progress index in comparison to each preceding archive entry is labeled with a "∆" after its name in the
table header (Example: "Vb
∆ " in Fig. 1). They are shown in the display only, and not read out via the inter-
face.
Fig. 1: Progress index display in the archive
Normally the counter advance corresponds to the flow (consumption) over one measurement period. This is
however not the case, where an archive row is added as a result of a specific event (i.e. resetting of the
clock or meter, displaying of an important status message) or if a data error is detected. Such an event is
indicated as follows:

EK280 Application Manual 12
Display Description
All values within an
archive row flash.
It is not possible to calculate a valid progress index due to a data error in the
current archive row. The data error is detected via checksum (CRC).
The progress index with
a "c" appended to it
flashes.
It is not possible to calculate a valid progress index due to a data error in the
preceding archive row. The data error is detected via checksum (CRC).
The progress index with
an "e" appended to it
flashes.
The displayed progress index does not refer to a full measurement period, as
the current or previous archive row was not entered as a result of
measurement period completion, but instead due to i.e. resetting of the clock.
Example of this: Fig. 1: "000000000.0000e" and "000000024.0000e". These
values would flash in the actual display.
2.2.2 Search function for checking archive entries
The measurement period archive and the daily archive contain several thousand and several hundred
entries respectively. Individual values from these datasets can be displayed for verification purposes, as the
