11.6.3 Calibration of the probe slope
» In the main menu, select 2B SLOPE
CALIB
» Enter the conductivity of the buffer
solution in the "BUFFER" field
according to the table on the bottle
label.
» Hold the sensor in the buffer solution
and wait until the "READ" value has
stabilized.
» press , to confirm the displayed
slope value and exit the parameter
and press , to return to the main
menu
or
» press to exit the parameter with-
out saving
The buffer value must not be 0, otherwise
the calibration is not saved.
11.6.4 Permeate set point calibration
With the assistance of the permeate conduc-
tivity measurement and a freely adjustable
limit value for the permeate conductivity, the
unit can be stopped and an alarm message
issued if the permeate quality is reduced.
» Select 3 LIMIT OUT in the main
menu
Press the arrow keys to select
whether the set point function should be
active or inactive.
» Confirm the selection with
If the set point function has been activated,
the program jumps to submenu "3B"..
By pressing the arrow keys
you can
set the max. set point
»
Confirm the selection with . The
program jumps to the submenu "3C".
If the permeate conductivity exceeds the limit
value set here during production, the system
stops, the alarm message "ALARM CON-
DUCTIVITY" appears on the display and the
alarm output relay picks up.
