7.4.2 Using ALMEMO
®
Memory Connectors
From version 5.73 it is possible with the data logger 3290-8 to record measu-
red values in removable external ALMEMO
®
EEPROM Memory Connectors ZA
1904-SS with capacities of 128kB (25,000 meas. values) or 256kB (50,000
meas. 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 data can be set via the measuring instrument
by connecting the memory connector to socket A1 and entering the baud rate.
The function ring memory will not be supported when storing data on the me-
mory 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 ´
FR
´.
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 by using the
keys
ENTER
, × Ø , Ö , × Ø , Ö (see 5.3).

If the internal data memory contains data when connecting the me-
mory connector the message ´
SCLr
´ will flash in the display and
prompt the user to delete the memory by using the key
Clr
. If the
data needs to be rescued the connector must be removed again
and the data must first be read out.
Each cyclic measurement must be terminated by using ´
STOP ´ as
the access to a closed set of data is usually not possible. Therefo-
re, the memory connector must not be disconnected when a mea-
surement is running! Single measuring point scans will be imme-
diately (automatically) terminated.
Open data can be rescued by using the command
f9 P04
as long
as no new measurement has been started.
Trigger and relay cables can also be connected to socket A1.
