Fixed Measuring Period; Memory Status, Delete Memory Content - Ahlborn ALMEMO 710 Operating Instructions Manual

10. Data logger
10.4.1 Start date and time, Stop date and time
A measuring operation can be started / stopped automatically at specified
times. ´Start date´, ´Start time´ and ´Stop date´, ´Stop time´ can be pro-
grammed via menu ´Settings´ > ´Data logger 3/4´; this can be reached via the
function ´Measuring start´ in menu ´Data logger´. If no date has been pro-
grammed, the measuring operation will be performed every day within the pe-
riod set. This is assuming of course that the current time-of-day has been pro-
grammed. Or, alternatively, instead of specifying the stop time, the fixed mea-
suring period itself can be programmed. (see 10.4.2)
The start and stop times can also be viewed in the main menu ´Data logger´ in
function ´Measuring start / stop´.

10.4.2 Fixed measuring period

To have a measuring operation stop after a certain period elapses it is also
possible, instead of programming the stop time, to program the ´Fixed mea-
suring period´ itself - in menu ´Settings´ > ´Data logger 3/4´.
After the measuring operation starts, the remaining time can be viewed in the
main menu ´Data logger´ in function ´Measuring stop´.

When recording to memory be sure to check whether a fixed mea-
suring period has been programmed to ensure that this does not in-
advertently cause recording to abort prematurely.

10.5 Memory status, delete memory content

While measured values are being recorded the memory capacity still available
is continuously displayed in the menu ´Data logger´ in function ´Memory sta-
tus´. By selecting this function in menu ´Settings - Data logger 4/4´ all memory
data can be viewed.
´Memory total´ indicates the total memory size - in KB for internal or in MB for
external (memory card).
´Memory free´ indicates the remaining memory capacity - in KB for internal
and in MB for external (memory card) - and the memory time - in the format
D.hh:mm - still available in the current scan cycle.
´Ring memory´ can only be activated for an internal memory; recording will
then be unrestricted in terms of time. If the memory is full the oldest measur-
ing operations will be overwritten.
There is also the function ´Delete memory content´.
However, before memory content is actually deleted, a confirmation window
will open; confirming will clear the storage medium completely; i.e. all files will
be deleted.
