For long-term observations it is better to choose the rH-value
as it compensates for fluctuations that a changing pH-value
causes. Select the desired display with the arrow keys and
confirm it with the
enter key
.
Afterwards, set the length of time that the information is shown
on the internal LC-display. You have a choice between 1, 2, 3
or 4 seconds. 2 seconds, for example, signify that the internal
display shows the date and time for 2 seconds, then the values
from sensor 1 and sensor 2 for two seconds, then the switch
mode of the sockets for 2 seconds etc.. Select with the arrow
keys and confirm by pressing the
enter key
.
Now set the length of time that the display is shown on an
external display panel. It is only of relevance if you have
connected an external display. Here too you can choose
between 1, 2, 3, or 4 seconds. 2 seconds, for example, signify
that the information on the external display is held visible for 2
seconds until the next details appear. The selection is
confirmed by pressing the
enter key.
You now find yourself back in the menu “SetMeasurement”.
From here you can now select the menu “Memory” or “Trend
period”. You can return to the main menu level with the
esc
key.
7.4.2 The menu “Memory”
The
iks aquastar midi
internal memory can store
4000 chains of measurements
. A chain
of measurements comprises date, time and the values of the connected modules. These
stored values can be transferred later on to a PC where they can be processed more
comfortably.
Select the menu “Memory” with the arrow keys and confirm with
enter
. Now you can make a few settings or adjustments.
The time interval at which the values are stored is set here. In
the example on the left, the values are stored every 15 minutes.
The input is confirmed by pressing the
enter key.
Here, the memory capacity still available is
displayed
(not
changed!). In this case there is still space available for 1038
chains of measurements (maximum 4000). If the figure is
getting close to zero then you should consider if it might be
better for you to transfer the data to a PC to prevent the oldest
chains of measurement from being over-written. Press the
enter key.
Now you are asked if you want to erase the memory. If you
select “Yes” then you have space for 4000 chains of
measurement again. However, the old measurements are then
irrevocably
erased.
