7.4.2 Memory Connector
The ALMEMO
®
2290-8 is the device that allows connecting external ALMEMO
®
EEPROM Memory Connectors ZA 1904-SS with capacities of 128kB or 256kB
(25,000 or 50,000 measured values). These memories do not require a battery
to keep stored data available. They can be removed, sent away and,
independent from the device they can be evaluated on a computer by means
of a readout interface (ZA 1409-SLK). The baud rate for the readout of data
using the readout interface can be set via the measuring instrument (see 9.1).
The function ring memory will not be supported when storing data on the
memory connectors.
The memory connector is plugged into socket A2 and will be automatically
identified and, as long as it is connected, will be used in place of the internal
memory. This will also be visible at the display of the memory capacity. Left of
the memory space a 2-digit connector number will be indicated. For
identification of the connector it can be programmed from 00 to 99 with keys

If the internal data memory contains data when connecting the
memory connector the message ´
SCLr
´ will flash in the display and
prompt the user to delete the memory by using the key
CLEAR
(see
7.4.3). If the data needs to be rescued the connector must be
removed again and the data must first be read out.You must not, in
the course of a measuring operation, either plug or unplug the con-
nector; the change will not be considered until the measuring operati-
on stops; i.e. if a connector is unplugged during a measuring operati-
on, all subsequent data for that operation will be lost
