4.1 Data base / RAM
The JN uses RAM cards as storage medium for large amounts of data.
RAM cards with capacities up to 4 MB (4096 kB) can be used. As a
disks, a RAM card must be formatted before it can be used. The
formatting procedure deletes all of the data previously stored on the
card and is irreversible. Approx. 1 kB is reserved on the card for system
information.
RAM cards are formatted by choosing the option
“RAM card”
from
the menu.
A list of further options appears along with information on the RAM
card.
Select
“Format”
and after the warning message has been confirmed
the RAM card is formatted. Once the formatting is finished the main
menu reappears.
Note :
The standard setting for RAM cards is 512 kB, if RAM cards of
different capacity are used this must be set under
“Configurate”
as
otherwise the card will be incorrectly formatted.
The RAM cards can be used for storage and for data base functions.
With the data base function, data is loaded from a PC (e.g. installation
data, customer data) and the measurements are added later in situ.
Once the measurements are completed, the data can be transfered
back to the PC in the correct form and under the correct area. To do
this an area of the RAM card must be reserved.
