BENNING MM 11
21
5.2 Memory function
The BENNING MM 11 is equipped with a measured value memory of
1.000 memory locations. These memory locations can be used to store
display values and retrieve the same at a later date via the display.
5.2.1
STORE
(Store display values)
By an extended operation (2 seconds) of the
-button
the
BENNING MM 11 is set into memory mode. The digital display
shows the symbol “MEM”. The display value is stored by re-pressing
the - button
(
STORE
). The stored value is indicated as a flashing
value in the subdisplay
, stating the memory location number. Display
values are continuously stored on memory locations 1 - 1000. A double
acoustic alarm sound signals a full memory store. By an extended
operation (2 seconds) of the
-button
(
STORE
), there will be a
switch back into normal mode.
5.2.2
RECALL
(Retrieve memory values)
By an extended operation (2 seconds) of the
-button
(RECALL)
the memory can be read out. In the digital display
the
symbol “MEM” and the stored measured value appears.
The memory location no. appears on the subdisplay
. The memory
locations 1 - 1000 are selected by means of the button (yellow)
and
the button BAR
, with an extended press of the button (2 seconds)
causing a fast run-through of the memory locations (10 memory loca-
tions/ second). By an extended operation (2 seconds) of the
-button
(RECALL)
there is a switch-back to normal mode.
5.2.3
Memory deletion
The memory content of the BENNING MM 11 is deleted by pressing the
button-
and simultaneously turning the rotary switch
out of
the “OFF” switch position.
5.3 DATA-LOG function
By an extended operation (2 seconds) of the button (blue)
the
BENNING MM 11 is set into
DATA-LOG
mode. The digital display
shows the symbol “LOG”. Pressing the button again (2 seconds)
switches back into normal mode. The
DATA-LOG
function provides for
an automatic storage of measurement series with up to 40.000 meas-
ured values. The measured values can be retrieved for further process-
ing at a later date via the display unit
or via the optical interface
. The scan rate which defines the period between two successive
measuring points can be selected from 0.5 seconds to 10 minutes.
Note:
- The RANGE button
and the automatic switch-off (
APO
,
A
uto-
P
ower-
O
ff) are not functional in this mode of operation.
- Each operation of the rotary switch
interrupts the
DATA-LOG
mode.
5.3.1
LOG-RATE
(Set scan rate)
If the BENNING MM 11 is in
DATA-LOG
mode, the scan rate is set
by pressing the button
(LOG RATE)
. The preset scan rate
is indicated in the subdisplay
and can be selected by means of the
button (yellow)
▲
and the button BAR
▼.
Selectable scan rates: 0.5, 1, 10, 30, 60, 120, 180, 240, 300, 360,
480, 600 seconds. Another press of the button
(LOG RATE)
confirms the scan rate and exits the setting mode.
5.3.2
DATA-LOG-IN
(Store data)
If the BENNING MM 11 is in the
DATA-LOG
mode, an extended opera-
tion (2 seconds) of the button
(DATA LOG)
starts the auto-
matic storage of the measuring series. The measured value storage
is indicated in the subdisplay
by means of the memory location no.
and a flashing symbol “-”. The highest memory location no. indicated
in the subdisplay
is 10.000. If the memory location no. 10.000 is
exceeded, counting restarts again at 0. and the bar graph display adds
respectively ¼ of the maximum deflection for 10.000 measured values
read in.
A renewed operation of the button
(DATA LOG)
interrupts the
measured value storage whilst simultaneously indicating “Pause” in the
subdisplay
. The maximum break period is 4095 seconds. In the event
of this period being exceeded the measuring series is continued after
4095 seconds. The break period can be utilised to set another scan rate
or to interrupt the measured value storage for a short period of time.
An extended press of the button
(DATA LOG)
exists the
DATA-LOG-IN mode.
If the memory is full (4 x 10,000 measured values), „FULL“ is displayed
in the lower display
2
and the measurement is stopped.
