3. Specify the input range: "Analog input range" parameter box. Set one of the two possible
current ranges:
– 4 to 20 mA
– 0 to 20 mA
4. Set the unit of the measured value: "Unit" parameter box. The following units can be set
depending on the measured value type
– "ppm": When changing the measured value type to the value "Gas", the "ppm" value is
– "%", "mg/m³" "mg/l", "g/m³", "g/l", vpm
– "u": "undefined unit"
5. Specify the start-of scale and full-scale value of the analog input range: Parameter boxes
"Start-of-scale value for 0/4 mA" or "Full-scale value for 20 mA".
The start-of-scale and full-scale values must always be identical to those of the device
feeding in. Check the corresponding values of the external analyzer or the sensor being
used.
For the input to be accepted, the start-of-scale value must be lower than the full-scale
value.
6. Enter the user-specific name of the analog input: "Designation" parameter box.
You can use a maximum of seven characters when entering the designation.
7. Read off the measured value: Display of the current analog input value according to the
current analog input parameter assignment.
Setting an analog input with the measured value type "Pressure", "Flow" or "Temperature"
If you set this measured value type, the "Gas" parameter box is omitted.
1. Main menu > "2. Settings" > "09. Inputs/outputs" > "1. Analog inputs" > "Analog input n"
The measured value type is set to the value "Pressure", "Flow" or "Temperature". The
units assigned to the measured value type are set in the factory and these defaults
cannot be changed by the user:
– Pressure: → hPa
– Temperature: → °C
– Flow: → ml/min
2. Specify the input range: "Analog input range" parameter box. Set one of the two possible
current ranges
– 4 to 20 mA
– 0 to 20 mA
