Parameter Possible settings Description
Temp. unit °C
°F
Setting for the temperature unit
Hold release 0 to 600 s
0 s
Prolongs the device hold when the hold condition no longer
applies
Alarm delay 0 to 600 s
0 s
Time delay after which an alarm is output
This suppresses alarm conditions that are present for a period
that is shorter than the alarm delay time.
Input Setting for the inputs
Cell const. Read only Displays the cell constant
Inst. factor 0.1 to 5.0
1.0

The effects of the distance from the wall can be corrected
with the installation factor →  29
Unit Auto , μS/cm, mS/cm Unit of conductivity
"auto" automatically switches between μS/cm and mS/cm.
Damping main 0 ... 60 s
0 s
Setting for the damping
Temp. comp. Off , Linear Setting for temperature compensation
Alpha coeff. 1.0 to 20.0 %/K
2.1 %/K
Coefficient for linear temperature compensation
Ref. temp. +10 to +50 °C
25 °C
Enter the reference temperature
Process check The process check checks the measuring signal for stagnation. An
alarm is triggered if the measuring signal does not change over a
specific period (several measured values).
Function On , Off
‣
Switch the process check on or off.
Duration 1 to 240 min
60 min
The measured value must change within this time as otherwise
an error message is triggered.
Observation width 1 to 20 %
0.0 %
Bandwidth for the process check
Analog output Setting for analog outputs
Current range 4-20 mA
0-20 mA
Current range for analog output
Out1 0/4 mA 0 to 2000000 μS/cm
0 μS/cm
‣
Enter the measured value at which the min. current value
(0/4 mA) is present at the transmitter output.
Out1 20 mA 0 to 2000000 μS/cm
0 μS/cm
‣
Enter the measured value at which the max. current value
(20 mA) is present at the transmitter output.
Out2 0/4 mA -50 to 250 °C
0.0 °C
‣
Enter the measured value at which the min. current value
(0/4 mA) is present at the transmitter output.
Out2 20 mA -50 to 250 °C
100.0 °C
‣
Enter the measured value at which the max. current value
(20 mA) is present at the transmitter output.
