Restricted Operating Menu / Description
To determine the precise cell constant (cc) of the sensor, place the sensor in a calibration solution (sample 1)
with a known conductivity and select the second menu option. The DULCOMETER
®
D1C displays the
conductivity it has calculated with the updated parameters. Press Enter when the value is constant.
Select the next menu option and enter the conductivity of the calibration solution (arrow keys). Press Enter.
The D1C displays the recalculated cell constant and saves the value.
The setting menu is inactive when “PAR2“ appears.
During the calibration, the metering is reduced to the set basic load and control stops.
The limit value monitor and the fault diagnosis system are reset. The standard signal of the “measured value“
output is frozen.
Parameter record
This setting menu can be used to temporarily enable additional parameters of the second parameter record
PAR2 to be edited (in addition to the parameters from the setting menu “measurement parameter setting?“).
I.e. the “limit setting?“ and “mA output 1 (2) setting?“ setting menus are enabled to allow editing of PAR2
(designation PS2) until you exit the series of setting menus from “parameter record“ to “general setting“.
It is possible to switch between the parameter records for operation using the “feed forward control“ contact
input, e.g. during a flushing process (contact open = PAR1, contact closed = PAR2). When switching between
the parameter records, the current parameter record in the setting menu “measurement parameter
setting?”, “limit setting?“ and “mA output 1 (2) setting“ is replaced by the other parameter record
(designation PS1 or PS2).
There is no access to the calibration menus in the case of PAR2 (designation PS2).
NOTE
• The designation PAR1 indicates that the parameter record 1 is actively measuring (contact
input “feed forward control“ e.g. open).
The designation PS1 indicates that the parameter record 1 can be edited.
Exception: The parameter record 1 cannot be edited while it is actively measuring
(designation PAR1). If your controller switches the D1C to parameter set 1 while it is being
edited, the D1C returns to the permanent display.
• PAR2, no control, no standard signal outputs.
