8.6 Data Memory (Option S)
With the option S the measuring instrument with built-in printer is equipped with
a 500kB data memory for ca. 100,000 measured values. The basic principles
for storing data in ALMEMO
®
devices are described in section 6.9 of the
manual. The memory organisation can be selected as linear or ring memory
(standard) (see manual 6.10.13.2). Ring memory means that old measured
values are overwritten when the memory space is occupied. In principle, all
measured values that are acquired during a measuring point scan are stored. If
the data should only be stored and not be provided online, the output mode ´
S
´
must be set (see 8.1). The stored data can be completely retrieved offline at a
later point in time or just an extract can be retrieved with any output format.
8.6.1 Memory Functions
For implementing the above options, special memory functions are available
that allow (only with regard to the memory output) for setting the output mode,
plot and time range. The functions do not have any influence on the device or
sensor programming. For this purpose, it is necessary to firstly select the
function MEMORY ´
MY
´ by using the key MEASURE The display will indicate
the previously stored measured value. By using the key CH
▲
the other
channels of the previous measuring point scan are also accessible.
