11.5.8.5 Memory time
An important parameter for data recording is the available
memory time
. This
depends on the free memory capacity available, the measuring rate set, the
scanning mode, and the number of active measuring channels. All these vari-
ables are clearly shown via the menu described.
Active channels

The ALMEMO 2590-3S/4S with its internal memory can continue recording in-
finitely, so long as in the next menu (see 11.5.9) the parameter
Ring memory
is activated. In this mode, as soon as the memory is full, the oldest data is sim-
ply overwritten; the most recent data is always available; (see Manual
6.10.13.2).

11.5.9 Starting and stopping measuring operations
A measuring operation can be started and stopped not only by pressing the ap-
propriate keys but also using numerous other methods; these are described
the the Manual, Section 6.6.
These operating instructions, in the 3rd data logger menu, describe the start
time and end time, the measuring duration, and the actions in the event of a
limit value being exceeded (see Section 12.12.2) and the relay and trigger vari-
ants (see Section 14.2).
Start time Start date, End time End date
A measuring series can be started and stopped
automatically at specified times. For this purpose
the
start time
and
start date
, and the
end time
and
end date
must be programmed. If no partic-
ular date has been programmed, the measuring
operation will be performed every day within the
set period. Or, alternatively, instead of specifying
the end time the
measuring duration
itself can be programmed. The total mea-
suring time since starting can be seen in the function
Measuring time
.
This is assuming of course that the current time-of-day has been pro-
grammed.
Sleep mode
takes no account of end time or measuring duration.
