The following alternatives are available for the
uninterrupted display of information
or directly, without a delay (however, this only applies to the LC display): By pressing the
del key the sensor readings are displayed directly
.
By pressing the "
Ø
" key,
time and
date
are displayed. The
switch positions of the sockets
are displayed by pressing the
"

7.3 The menu “Calibrate”
Bitte beachten Sie, daß pH- und Redoxelektroden kalibriert werden müssen, damit eine
korrekte Messung erfolgt. Diese Sensoren sollten auch von Zeit zu Zeit nachkalibriert
werden (siehe Punkt 13.3 Tips zum Kalibrieren)!
A sensor test is carried out once the calibration process has been completed and for
automatic recognition of the calibration solutions. At the end of this you will
normally
receive the message “
Sensor o.k.
”. However, if you get the message "
Buffer not
recognised
" there are 2 possible reasons: either you are using an old or incorrect
calibration solution or your sensor is defective or wrongly connected. This can also be the
cause of the error message “
Sensor error
” but in this case a defective sensor is more
likely. Please contact your specialist dealer
.
Select the menu
“Calibrate
” from the
main menu
and confirm
your choice with

7.3.1 Calibrating the pH-sensor
If you have an
iks
aquastar midi pH,
the display will appear as
shown on the left. If you have an
iks aquastar midi Redox
, you
can jump straight to Section 7.3.2. Confirm your choice with
enter
. Several general settings for the relevant sensor will be
requested before the actual calibration process starts. The
system requires a few details to compensate for the pH-sensor's
dependence on temperature.
If
no temperature sensor
is connected to your system you will
be requested to enter the tank temperature manually. Confirm by
pressing the
enter key
.
If a
temperature sensor
is connected to your system then the
tank temperature
doesn't have to be entered manually
but can
be included automatically.
To do this,
don't
select the function “Input” but select the
appropriate temperature sensor (sensor 1) with the help of the
arrow keys. The selection must be confirmed with the
enter key
.
Now you have to enter the temperature of the buffer solution. If
you can't measure the temperature the easiest thing to do is to
let the bottle of calibration solution float in the aquarium water for
a few minutes. The temperatures of the aquarium water and
those of the calibration solutions will then align themselves
enabling you to enter the temperature of the aquarium or let the
temperature sensor do it for you. Of course it's also possible to
use the temperature sensor to take a very precise measurement
