SD card
The device is equipped with an SD card interface. The SD card can be used as a storage medium
for measurement data in order to be able to store larger quantities of data over the long-term, for
example. In addition, an SD card with a security key is required to carry out local firmware updates
on the device. More detailed information can be found in the "Firmware update" chapter.
Only Micro-SD format memory cards up to a capacity of 32GB can be used.
Although the memory access and the minimum reading and
writing speed for SD cards of this type are standardised, not all
manufacturers' variants are compatible! Ask your supplier about
compatible and tested manufacturers.
The SD card interface operates in accordance with the Push-Push principle, i.e. the card is
inserted into the slot and latched into place with a light push. Another push on the card unlatches it
and allows it to be withdrawn again.
