The percentage indicates the fraction of data already transferred. If the operation is carried out correctly it will be possible to read
the following message:
otherwise, if for instance there is no more place in the storage of the Download module (where the data are being dumped) or an
error has occurred in the connection or something else, the following message will appear:
The Download operation ends after an acoustic signalling. Being in the Download mode, it is possible to go to the other modes
(for example, to check possible new alarms) by pressing the relevant buttons. In this case the user will be informed on the state
of the Download by an arrow on the right bottom corner of the display. By pressing the two and buttons as long as the
arrow is present, it will be able to return into the Download mode and display the mask relevant to the phase being reached by
the data transfer. When being in the Download mode, the temperature sampling is in any case active.
Example of data print by Download (table print)
The following page is a model of printing of the data recorded by a Datalogger and dumped on a disk through the CAREL
Download modules – DLOGSER000. From October 1997 the portable module DLOGPC0000 will be available. Both modules are
managed by Windows™.
In fact each line of the table corresponds to a recording, of which the date, the hour, the temperature measured by the probes, the
state of the digital inputs and of the relay outputs, the information on the Power ON,
on the time change and the alarms are reported.
Furthermore, the data that are included within particular ranges (“fi lters”) selected by the user via software are pointed out in italic
boldface. Thus, it is possible to detect which temperatures have exceeded the high or low temperature thresholds or which are the
data stored by the Datalogger at a certain time interval.
In the model page here reported the following fi lters were selected:
• Selection 1: the data stored between 12:00 and 13:30 hours of the 18/02/1997 day have been sought
• Selection 2: for the probe 1 a high temperature threshold equal to -17.5°C has been selected, equal to the relative threshold
selected in the Datalogger (and so in the Alarm column the corresponding alarm symbol appears).
• Selection 3: for the probe 2 a low temperature threshold equal to -19.0°C, different from the relevant to the threshold selected
in the Datalogger (as a consequence, in the Alarm column no alarm symbol appears).
• Selection 4: the probe 2 has been confi gured only at 9:00 hours of the 18/02/1997 day, and therefore there are temperature
recordings relevant to it only beginning from this hour. In the previous recordings the character “-“ is reported to indicate its
absence.
For a two channel Datalogger model (such as the one presented in the example) the absence of the probes 3 and 4, of the digital
inputs 3 and 4 and of the digital output 2 is similarly reported.
At the end of each page the serial number and model (2N=2 channels, 4N = 4 channels) of the Datalogger, with which the data
have been stored, the name of the operator in charge of the instrument, the signature and date at and hour in which the print has
been carried out are reported.
A space is also provided for the authentication of the document by the fi rm that is the holder of the Datalogger, that may
personalize the print by inserting its own name (“Supermarket “XYZ” in the example) at the head of each page, near the logo and
the writing “Datalogger CAREL”.
Finally it is worth noting that the print is optimized if the interval between two successive recordings is of 15 minutes. In this case
to each page correspond the data being recorded throughout 24 hours.
Note: it is possible to print the temperature data graphic on a A4 format sheet. Please fi nd an example of graph print on page 20.
