External Memory Connector Fitted With A Memory Card; Memory Capacity Display - Ahlborn ALMEMO 2470-1S Operating Instruction

ledged by pressing ´OK´, the question ´CMEM´ appears. If ´OK´ is now pressed
the memory content will be cleared and the measuring operation starts. If ´ESC´
is pressed instead, the memory content is not cleared and measured value re-
cording is continued - but incorrectly configured (units, measuring range).

11.2.2 External memory connector fitted with a memory card

Memory capacity on the ALMEMO
fitting memory connector ZA 1904-SD and a conventional micro SD memory
card. Measured data is written to this memory card via the memory connector;
this data is in table mode and standard FAT16 format. The SD card can be
formatted and its contents can be read out or deleted- using virtually any SD
card adapter on any standard PC equipped with a card reader. This data can
also be imported into MS-Excel or into Win-Control.
Connecting the memory connector
The memory connector fitted with a memory card can be plugged in at socket
A2; it will be recognized automatically. The available memory capacity ´FrEE´
is shown in MB. Before the start of any measuring operation an 8-character file
name can be entered via the interface (e.g. with the AMR-Control software). In
the absence of a user-defined file name, the default ´ALMEMO.001´ or the name
most recently used will be suggested automatically. So long as the connector
configuration is not altered, any number of measuring operations can be saved
- either manually or cyclically - all in the same file. If, however, the sensor con-
figuration has been changed since the last measuring operation, a new file will
be created; and, if no new file name has been programmed, the index in the
file name extension will automatically be incremented by 1, e.g. ´ALMEMO.002´.
Similarly, if the file name now entered already exists, a new file will be created
with the same file name prefix but with an incremented index.
To check that the memory connector is functioning properly there is an LED in-
corporated in the end of the handle; this indicates the following states:
No memory card is detected.
●
Data is being recorded.
●
Data is being read out.
●
Please ensure, when plugging in the connector, that the card remains

latched in position. Memory cards do not support ring memory mode.
In the course of a measuring operation the external memory must not
be unplugged; all temporarily buffered measured values would be lost.

11.2.3 Memory capacity display

In normal circumstances memory capacity display ´FrEE´ shows the still free
capacity of the internal memory in KB (kilobyte).

city of the memory card in MB (megabyte).
