channel. In both modes all measured values can be saved and output at any
time. With both the following functions continuous saving to memory and con-
tinuous output of measured values can be activated at the measuring rate.

Memory time
12.5.8.5
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 varia-
bles are clearly shown via the menu described.
Active channels for minimum cycle and memory time :
Available memory time :
The ALMEMO 2590-4AS with its internal memory can continue recording infi-
nitely, so long as in the next menu (see 12.5.9) the parameter Ring memory is
activated. In this mode, as soon as the memory is full, the oldest data is simply
overwritten; the most recent data is always available; (see Manual 6.10.13.2).
Linear memory Data is not overwritten :

Starting and stopping measuring operations

12.5.9
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 13.12.2) and the relay and trigger variants
(see Section 15.2).
Start time Start date, End time End date
A measuring series can be started and stopped au-
tomatically at specified times. For this purpose the
start time and start date, and the end time and
end date must be programmed. If no particular 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
