5 Installation
5.1 Sensors
5.1.1
Sensor type
: Display of the used sensor type (e.g. Well IR)
5.1.2
Dimension
: Choose the measurement unit (FNU, NTU or ppm)
5.1.3
Flow
: Select a flow measurement method.
5.1.3.1
Flow measurement
: Select the type of flow sensor if a flow sensor is
installed. Possible flow sensors:
5.3.1.2
Slope
: Only available if deltaT flow has been selected. Increase or
decrease the slope to adjust the sample flow, see
taT Flow Sensor (Option), p. 46
5.1.4
Offset
: A manual offset of the measured value can be set.
Range: -1.000 to +1.000 FNU/NTU
5.2 Signal Outputs
Note:
The navigation in the menu <Signal Output 1> and <Signal
Output 2> is equal. For reason of simplicity only the menu
numbers of Signal Output 1 are used in the following.
5.2.1 & 5.2.2
Signal Output 1 & 2:
Assign process value, the current loop range
and a function to each signal output.
5.2.1.1
Parameter:
Assign one of the process values to the signal output.
Available values: Meas. value, Sample flow.
5.2.1.2
Current Loop:
Select the current range of the signal output.
Make sure the connected device works with the same current range.
Available ranges: 0–20 [mA] or 4–20 [mA]
5.2.1.3
Function:
Define if the signal output is used to transmit a process
value or to drive a control unit. Available functions are:
Linear, bilinear or logarithmic for process values.
