Data Transmission - VOLTCRAFT Energy Logger 4000 Bedienungsanleitung

12. Data transmission

The energy cost measurement device has an internal, non-volative data memory with a capacity of up to 6 months.
The display shows the remaining capacity in %. If this value drops to 2%, the MEM display starts flashing. It is now
necessary to read out and delete the required data memory, as otherwise no data can be recorded.
During data transmission, the measurement device can be operated for mesurement conversion. The
SDHC card must not be removed or the measurement device unplugged. This results in a risk of data loss.
An optional SDHC card with the following characteristics is required for reading out:
• memory size at least 512 MB, max. 32 GB (4 GB recommended)
• storage format FAT 32
• not write-protected
• Minimum 5 MB free storage capacity
• energy data previously saved on the card must be deleted
Proceed as follows to start data transmission:
• Pull the plastic cover on the SDHC card shaft unit (6) out to the side.
• Insert the optional SDHC card in the slot as illustrated. The chanfered
corner points downwards.
• Push the card shaft unit into the machine.
• The SDHC card symbol is displayed. If the symbol cannot be seen,
check whether the card is fully inserted.
• Press the „Continue" arrow key (7) in order to start data transmission. A flashing arrow singalises data transmission
and the memory information runs from 0 to 99%.
• The data is transferred to the card. Depending on the use of various SDHC cards and the size of the stored data,
this can lead to a longer data transfer sequence, although the machine already shows that the storage has been
completely accomplished. For this reason, you should leave the SDHC card several seconds in the energy logger,
even after the display indicates that the transfer has been completed. Then the SDHC card can be removed. Close
the cover of the SDHC card drive (6).
To switch the measurement displays, click the „MODE" (5) key for the „Continue" arrow key (7). Every time you press,
you switch the display.
