7.4 Data Memory
The basic information with regard to data storage in ALMEMO
®
devices is
given in the manual section 6.9. The memory organisation can be reconfigured
from linear to ring memory (see manual 6.10.13.2).
7.4.1 Data Acquisition
Switch-on and Switch-off of the Storage within the Measuring Cycle
If the memory has been activated in position MEAS. CYCLE by using the key
CH ▲
(see 7.3.2) each measuring point scan (exception: continuous) is stored.
This is applicable for each scan in the measuring cycle, print cycle and a
manually started scan (even when the measuring cycle is zero). Outputs to the
selected interface will still be performed.
Switch-on of the Storage within the Print Cycle
If the output channel has been set to ´S´ by using the key
CH ▲
while in
OUTPUT CYCLE (see 7.3.1) all outputs that are normally transmitted to the
interface will be stored in the memory, i.e. measuring point scans in the print
cycle or manually started scans and also alarm outputs (e.g. exceeding of limit
values) in the measuring cycle.
For starting a cyclic storing the key
START/STOP
must be operated. If
measured values are stored the arrow ´
MEMORY
´ is indicated for control
purposes, e.g. continuously during automatic scans and only during the scan if
the scan has been manually started.
Stopping the storing is performed by pressing the key
START/STOP
again.
Displaying the Data Memory:

The display shows the last stored measured value
of the input channel.

If the memory is full the display indicates:
Further measured values will no longer be
stored when in the linear memory. Old
values will be overwritten when in the ring memory.
