12.2 Measured value memory

The basic information on saving data in ALMEMO devices is provided in the
®
Manual, Section 6.9. The ALMEMO 5690-2M system (option S only) incorpo-
rates an internal 512-KB EEPROM with sufficient capacity for 64000 to 100000
measured values (depending on the number of channels). In the event of a fail-
ure in the supply voltage the measured data is retained intact. The EEPROM
can be configured either as linear memory or ring memory; (see Manual
6.10.13.2). Or, alternatively, a SD card can be used in the default slot for this
purpose (4).

12.2.1 Memory with memory card

Any conventional SD memory card (or micro SD with adapter or a multimedia
card) can normally be used for external memory. This offers virtually limitless
memory capacity; data can thus be evaluated elsewhere as and when required.
The memory card can be formatted and its contents can be read and deleted
via any normal PC using any card reader. Measured data can be imported into
MS-Excel or into Win-Control (the accompanying measured value software).
The memory card is inserted in slot (4) on the front panel; it is recognized auto-
matically. You can verify this in the menu (see 12.2.2) and

suring operation it must not be unplugged; this would cause temporarily
buffered measured values to be lost.

File name (maximum 8 characters)
Before starting any measuring operation you can, in the function , en-

ter an 8-character file name. In the absence of a user-assigned file name, the
default name ´ALMEMO.001´ or the name most recently used will be suggested
automatically. So long as the connector configuration is not altered, you can
save several measuring operations, either manually or cyclically, also with nu-
merical assignment, all in the same file (see 12.2.3).
If, however, the connector configuration has been changed since the last
measuring operation and if no new file name has been programmed, then a
new file is always created and in so doing the index in the file name extension
is automatically incremented by 1, e.g. ´ALMEMO.002´. Similarly, if the file name
