Each time a key is pressed again the measured values will be processed in the
same way with the associated actual measuring duration.
14.5.5 Cyclic saving of all measuring points
For cyclic measured value recording either the output cycle or the scan cycle
must be programmed in the next menu and saving-to-memory must be acti-
vated accordingly (see Manual 6.5.1.2). The 'save-to-memory cycle' function
will then indicate the cycle being used for data logging (s. 11.4). Having se-
lected this function you can specify the cycle directly (s. 9.5).

Save-to-memory cycle
Memory cycle
: 00:02:00 s
The procedure for setting the data and time-of-day is described in Section 16.1.
The measuring operation can be started by pressing
<START>
and stopped by
pressing
<STOP>
. Each time a measuring operation starts, if the device has
been so configured, the maximum, minimum, and average values of all mea-
suring points will be cleared (default, see 16.9).
To
start a cyclic measuring point scan
<START>
The following symbols will be highlighted continuously in the status bar, i.e. so
long as the measuring operation is running (s. 9.2).
The START arrow lights up.

14.5.6 Memory capacity, memory output and clearing
When measured values are being recorded the 'memory capacity free' function
continuously displays the memory capacity still available. Selecting this func-
tion enables two softkeys, one for direct memory output and one for memory
clearing.
Function
memory capacity free e.g.
Memory free: 238.4 kB
Output memory in table format
<PMEM>
Completely delete the memory card’s contents
<CMEM>
If an SD memory card is being used the device itself can only read out in table
mode the measured data contained in the file most recently used (s. 14.5.2). For
the duration of memory output the LED on the handling end lights up continu-
ously. The most sensible approach is to remove the memory card and copy the
files via the SD card adapter and USB card reader directly onto a PC. These
can then be imported either into MS-Excel or into Win-Control (as of V.4.8.1).
