The Parameter Setting menu is divided into three
submenus: Viewing level (view), Operator level
(opl) and Administrator level (adm).
The passcode protection protects access to calibration,
maintenance, Operator and Administrator
level. The passcodes can be edited or disabled on
the Administrator level.
Can be defined for identifying the Process Unit;
can be displayed in the diag menu or read out via
remote interface
With temperature compensation enabled, the
measured value is calculated for the reference
temperature (usually 20 or 25 C) using the temperature
coefficient.
User defined sequence for cleaning the cell or
other sensors; controls contacts ”probe”, ”rinsing”
and ”cleaning”
User defined time at the beginning of the rinsing
cycle, after closing of contact ”probe”, before closing
of contact ”rinsing”
and keys for selecting menu lines or entering
numeric digits
Two small displays that appear at the lower left
and right sides of the main display during measuring
mode. The process variables displayed can be
selected using / and / .
User defined time during which contact ”rinsing” is
closed at the end of the rinsing cycle
With temperature compensation enabled, the
measured value is calculated for the reference
temperature using the temperature coefficient.
Calculates the measured conductivity value for a
reference temperature.
”view” – menu level of parameter setting; display
of all configuration settings, no editing possible
Position between ”Second Rinsing” and ”Measurement
Lead Time” where the probe remains as long
as a start current of 10 to 20 mA is applied to the
current input (only when current input has been
set as control input)
Alarm message and NAMUR contact;
means that measuring equipment still operates
properly but should be maintained, or that certain
process parameters have reached a value that
requires intervention.
Warning is not enabled during ”functional check”.
