Checking/Setting
routine
1
In the measured value display:
Press
<C>
.
Note: The states of all relays and
current outputs linked with the
measured conductivity value are
frozen during the checking/setting
routine.
2
Immerse the conductivity
measuring cell in the control
standard.
The following values are shown on
the display:
– Upper line: The measured
conductivity of the control
standard
– Lower line: The selected cell
constant
3
If the measured conductivity
deviates from the set value
(= 1413 µS/cm), the cell constant
can be changed until the set value
or the nearest possible value is
displayed (1 digit of the cell
constant roughly corresponds to a
little more than 1 µS/cm) with
<UP><DOWN>
.
4
Put the conductivity measuring cell
back into the measuring position.
5
Press
<ENTER>
or
<M>
.
The display switches to the normal
measured value display.
The states of all relays and current
outputs linked with the measured
conductivity value again follow the
measured value.
