The instrument is supplied with the default configuration specified in
Setting up
, page 14.
To modify the default configuration and adapt it to specific applications follow the diagram below.
Select the nominal value of cell
constant
to be used
. If the exact
value is known, it can be directly
entered, avoiding the calibration
procedure.
Selection of the functioning
values of the corresponding
relays.
Input “
ON
” (closed contact).
Output “
OFF
” (open contact).
Selectable values between
0.0 µS and 200 mS.
Select the time before the
alarm
activation.
Selectable between 1 to 99 min
or hours. 0= deactivated.
Select the conductivity values
corresponding to the
Current
Output
(4 mA and 20 mA).
Selectable values between
0.0 µS and 200 mS.
Selection of the current output
when the instrument is in Hold
state: fixed at 21 mA or at the
mA corresponding to the last
measured value.
Selection of the working
language
: English, German,
Spanish, French, Italian,

Note
: When programming, the instrument is
in hold state:
• The contact relays are open.
•
The current output is frozen at 21 mA.
To quit the hold state it is necessary to return
