Data backup / limited service life
There is a possibility of loss of data with all types of
data storage. Data loss can be caused by damage
to hardware, software, or unauthorised access etc.
The operator of the device is responsible for
backing up data recorded by the data logger. This
should be done in accordance with the national
and international requirements, regulations and
standards applicable to the operator of the device.
Define and document this data backup in a backup
or recovery plan.
The manufacturer of the device is not responsible
for backup or recovery of data.
SD cards only have a limited service life. This
service life is based, for example, on the general
ageing of the SD card and depends on the
memory technology (flash memory) of the funda‐
mentally limited number of write processes. Bear
this in mind with your data backup strategy and
ensure that you regularly replace your SD card.
The controller supports the following log books as standard:
Calibration log book
n
Error log book
n
Access flap to the SD card slot
Always keep the access flap to the SD card slot
closed during operation. If the access flap is open,
extraneous matter, like dust and moisture, can
enter and cause damage to the controller.
