Operating mode of the SD card and USB stick
Without affecting the internal memory, data packages are copied block-by-block to the SD card.
Tests are also made to determine whether the data have been written without any errors. The same
happens when storing the data on the PC with the PC software contained in the scope of delivery.
The data, monitored against manipulation, are available here. If you wish, you can export these data
to other programs, such as MS Excel
®
, without losing the protected data basis.
The use of a USB stick is only recommended if certain data ranges should be copied. The USB stick
is not designed for continuous measured value storage.
Notes:
• Only use new, formatted SD cards recommended by the manufacturer (see "Accessories", Section
8). Any data on the SD card or USB stick are overwritten once the card/stick is inserted into the
slot.
• The SD card or USB stick memory being written to is shown in normal operation at the top right
of the display ("SD: xx%" or "USB: xx%")
• Dashes "–" on this display mean that no SD card is inserted.
• No information is output if no USB stick is connected.
• The SD card should not be write-protected.
• Prior to removing the external data carrier, select "Extras –> SD card (or USB stick)–> Update".
The current data block is closed and saved to the external data carrier. This ensures that all
current data (until the last save) is included on it.
• Depending on the configuration of your unit (see "Setup –> System –> Ext. memory –> Warning
at"), an acknowledgeable message on the display informs you that the data carrier has to be
changed before the external data carrier is 100% full.
• Your unit knows which data have already been copied onto the SD card or USB stick. Should you
ever forget to change the data carrier in time (or if no SD card has been inserted), the new external
data carrier is filled with the missing data from the internal memory - in as far as the data are still
available there. Since measured value acquisition/registration has highest priority, it can take
several minutes until the data are copied from the internal memory to the SD card or USB stick.

Data analysis and visualization using PC analysis soft-
ware
The analysis software offers centralized data management with visualization for recorded data. This
allows the complete data of a measuring point to be archived, e.g.:
• Measured values
• Diagnostic events
• Protocols
Data can be read using USB, RS232/485 or Ethernet. The data already stored on the SD card
or USB stick can be transferred to the analysis software.
There are 2 different analysis software packages for this task:
• Reporting Software (incl. SQL database)
• PC Operating Software supplied.
6.10.1
Reporting Software (incl. SQL database)
The Reporting Software features a practical and convenient user interface with an assistant that
guides you through the individual operating steps. In contrast to the delivered PC Operating
Software, the Reporting Software stores the data in a SQL database. The database can be operated
locally or in a network (client / server). You can install and use the free Postgre
SQL database
supplied.
The Essential and Professional versions can be ordered as accessories Page 121.
For details, see the Operating Instructions on the Reporting Software provided.
