8. Data Memory
The basic information with regard to data storage in ALMEMO
®
devices is
given in the manual section 6.9.
A new feature is the possibility of saving several measuring operations with dif-
ferent configurations; however, to use this facility the ring memory mode must
not be set; (see Manual, Section 6.10.13.2). With each new start, the configu-
ration is checked; if it has changed, the new configuration is saved. The meas-
uring operation is also automatically assigned a number; (see Section 8.3).
Each configuration requires a storage capacity of 808 bytes. As, on principle,
only one configuration can be allowed in a measurement file, the memory
output into a table format is cancelled with each new configuration. The next
measurement must then be selected by its number or the time/date.
8.1 Memory Extension through Smart Media Card
As an option the data logger 2590-9 provides a slot for a standard Smart Media
Memory Card with 8MB or 32MB memory space. As a result, the memory
capacity is extended to 1,6 or 7,2 million measured values. Furthermore, it is
often useful when the data logger can remain at one measuring location and
data can just be taken on a memory device and evaluated somewhere else.
Please consider the following characteristics when using external
memories:
The function ring memory will not be supporte.
If the internal data memory contains data when connecting the
external memory the message ´CMEM´ will be displayed in the
function ´No: -- Free´ and prompt the user to delete the internal
memory by using the key <CMEM>.If the data needs to be rescued
the external memory must be removed again and the data must
first be read out.
Additionally, the external memory modules can be identified with a
two-digit number.
It can easily be entered in function ´No: 00 Free:´.
All measuring operations, including manual scans, must be termi-
nated with <
STOP
>. Data not thus terminated may be saved in in-
complete form or may be overwritten with the next measuring
operation.
Therefore, the external memory must not be removed when a
measurement is in progress!
