To return to output cycle (00:01:00):
<RESET>
s. 16.7.3
To start a cyclic measuring operation (if cycle >0) :
<START>

s. 14.5.4
12. MEASURED DATA SCANNING AND OUTPUT
Repeated measuring channel scans are needed in order to continuously moni-
tor and acquire measured values from all measuring channels, to record maxi-
mum / minimum values, to detect limit value infringements, and then to output
all this data either via the interface or to memory. With standard sensors this is
performed at the 'sampling rate' (normally 10 mops, s. 16.7.1). With the new
D7 sensors there is also a superordinate 'scan cycle', with which not only stan-
dard sensors but also all D7 sensors with their fully individual measuring
speeds are acquired (s. 16.7.2). Output can be performed using this 'scan cy-
cle' or at more prolonged cyclic intervals using the 'output cycle' (s. 16.7.3). For
certain applications output can also be initiated manually at specifiable points
in time.
Cyclic output
For cyclic output via the interface or to memory either the 'output cycle' or the
'scan cycle' must have been programmed and the output configured appropri-
ately (s. 14.5.7). Once cyclic output has started all measured value scans are
output cyclically in table format (see Manual 6.5.1.3).
To start a cyclic measuring point scan <START>
The cycle timer should then be seen counting down until the next cycle.
To stop a cyclic measuring point scan <STOP>
Once-only output
If the output cycle is deleted, a once-only measuring channel scan can be initi-
ated by pressing key <MANU> (see Manual
6.5.1.1
).
Once-only manual measuring point output <MANU>
Each time a key is pressed again the measured values will be processed in the
same way with the associated actual measuring duration.
13. USERMENUS
Despite these flexible combinations of measuring menus and function menus
there are still certain applications where an individual collection of functions
might be preferred (s. 14). This is the purpose of user menu
U2 Data logger
;
these can be assembled and configured completely freely using the ALMEMO-
Control software (s. 11.4). You can choose the functions you require from the
following list and arrange these on the display exactly as you wish; the only re-
striction is the available space, namely 7 rows.
