Tables

When a file of stored data is opened, this is displayed as a table. Each row of the table corresponds to an
acquisition of data made by the Datalogger, and consists of various fields:
1. Date: date (day/month/year) of the data acquisition;
2. Time: time (hours:minutes) of the data acquisition;
3. T1 ÷ T4: temperatures read by the configured probes (the symbol "-" indicates that the probe relevant
to that column was not configured at the moment of data acquisition). The 2N model Dataloggers have
2 channels, and probes 3 and 4 are always considered as non-configured by WinLog;
4. DI1 ÷ DI4: status of digital inputs. "OFF" indicates that the input is in the normal non-alarm condition,
that is, open if configured as normally open, and closed if configured as normally closed. "ON" indicates
that the input is in alarm condition, that is, closed if configured as normally open, open if configured as
normally closed. If the input is configured for defrosting, "OFF" indicates that the defrosting is not active,
while "ON" indicates that it is active.
In the two-channel Dataloggers there are only two digital inputs (DI1 and DI2). Therefore, the symbol "-"
is displayed in the table at the points corresponding to the absent inputs DI3 and DI4;
5. DO1: status of the alarm relay. "OFF" indicates that the relay is de-energised (the alarms are absent or
they are in "known" status); "ON" indicates that the relay is energised (active alarms);
6. DO2: status of the operating relay. Present only in four-channel model Dataloggers;
7. P.On: (Power On) signals with "POn" the first element of data acquired after a power failure;
8. T.c: (Time changed) signals with "T.c." the first element data acquired after adjusting the clock
(for example, when the time is changed from solar time to daylight saving and vice-versa).

Filters

The filters window is opened by clicking on the icon
allows analyses to be performed on the data, carrying out searches based on various selection criteria
(filters). The filters available are:
1. According to date: it possible to search all the acquired data based on a starting date and an ending
date (both of which can be selected);
2. According to temperature thresholds: for each probe it is possible to search all the data with a temperature
greater than a given high temperature limit and less than a given low temperature limit.
The data searches available are started by clicking on the "Apply" button. All data meeting the criteria are
highlighted with double apexes. If the "Filters only" option is not selected, all the file data will be shown in the
table, both highlighted and non. Conversely, if the "Filters only" option is selected, when clicking on the
"Apply" button, only the (highlighted) data satisfying the filter criteria will be displayed in the table. The "Clear"
button allows the table to be reset, by clearing all the highlighting symbols. Each filter may be enabled or
disabled by pressing the button to its left ("On" = filter enabled, "Off" = filter disabled).
The "Chronological order" button starts a check on the file data sequence, verifying that it is displayed in
chronological order (with a tolerance of two hours). A positive outcome of this check is indicated by "Ok"
appearing after the words "Chronological order". A negative outcome is shown by "Not Ok". This option must
be matched to the date filtering to be certain that different data (that is, acquired at different moments) do not
correspond to the same date and time.

Print table

By clicking on the icon
, a window (Fig. 12) of print options for the tables is activated.
The possible selections are:
1. To print filtered data only: enables printing only of the data in the table which has been highlighted by
applying filters, and omits the non-highlighted data.
Independently of whether this option is selected or not, the data highlighted by filtering is printed in
bold italic, making it distinguishable from the rest.
2. New page every new day: a new page is printed for every new day of data. In this way the print-out is
easier to read, especially when the file data is acquired by the Datalogger at 15 min. intervals.
This produces an optimised print-out.
If this print option is not required, it should be remembered that one page corresponds to 96 data items.
These two options are mutually independent.
An example of a page printed with WinLog is shown in Fig. 13. As can be seen, a space is provided for the
text selected by the user at the top left, while in the box at the page bottom the Carel logo can be replaced by
a customised logo (see point 4 of the Options menu). The other fields of the box are reserved for the serial
number, model and operator's name relative to the Datalogger which recorded the data, the date and time of
the PC which performs the print-out, a signature and if necessary the stamp of the firm operating the
Datalogger.
In the example in Fig. 13 the following areas of the print-out are highlighted, which correspond to some
examples of filtering:
1. Selection 1: a search has been performed for data stored between 12.00 and 13.30 on 18/02/1997;
2. Selection 2: for probe 1, a high temperature threshold of -17.5 °C has been selected;
3. Selection 3: for probe 2, a low temperature threshold of -19.0 °C has been selected;
4. Selection 4: probe 2 was configured at 9.00 on 18/02/1997, and therefore the temperature readings
relative to this probe are available only from that time. In the previous readings, the "-" character is
printed to indicate the absence of data.
For a two-channel Datalogger (as the one in the example), the absence of probes 3 and 4, of digital
inputs 3 and 4 and digital output 2, is highlighted in the same way.
To print the page shown in Fig. 13, the "New page per day" option has been selected, but not the "Print only
filtered data" option. As a result, both data highlighted in bold italics (data satisfying filter criteria), and lines
that do not contain any filtered data are printed. In Fig. 14, the same page has been printed, yet in this case
printed with both options selected.
