Micro-SD card replacement
The
Vigilant
unit has an internal micro-SD card where all trend data, spectra, waveforms, etc. are
permanently stored. The data is collected during normal operating measurements of the equipment.
Other data such as measurement settings, system and users are also stored in the card.
Although the system has several hardware and software features intended to preserve the integrity of
the storage system, storage units based on flash technology are fragile by nature. They all have
relatively high failure rates.
Although most of the times faults affect unimportant blocks of data, eventually the main database of
the system may get damaged, or even the boot partition of the card may get corrupted. In such events,
it may become necessary or convenient to replace the micro-SD card.
Vigilant
instruments are supplied with 4GB cards of industrial range (pSLC) formatted in FAT32.
Although the system is supposed to be compatible with almost any microSD card format, it is
recommended to contact
Vigilant
so that it can provide you with a suitable replacement for your card
in case you need to change it.
In case the system detects an incorrect type of card or without the appropriate format, the device will
start up with the storage deactivated. From the system menu or from the Recovery mode it is possible
to carry out the initial formatting in principle of any micro-SD card.
To access the microSD card, you must first remove the battery from the computer. Once the battery is
removed, the ca
rd’s connection tray is in the accessible hole below it.
The tray shows two marks where you have to slide the cover of the same, one to open the
compartment, and in the other direction to close it. You can slide this cover with the help of a
screwdriver.
