11 - Unit
SETUP - 11 determines the measurement unit to be displayed. The following units can
be selected:
•
Analysis-unit-package - pH, mV, mS/cm,

Modification of the measurement unit will have consequences for other SETUP-level
values. Please note that the span has to be adapted as well; the calculation is not done
automatically.
12 - Decimals
This setting determines the number of digits following the decimal point. The following
can be selected:
•
0000
•
111.1
•
22.22
•
3.333
13 - Offset
The unit needs to know the value at minimum signal, in most applications this is zero (0).
For ORP applications however, the offset can be set to -1500.
The following offset can be programmed:
•
- 1500...+3000
To program a negative offset value you have to press the middle and right button
simultaneously.
14 - Span
With the span, the sensor signal is converted to a certain value. The span is the
measuring range from the offset (value at 4 mA) to the value at 20 mA.
The following range can be programmed:
•
0.001...+3000
15 - Filter
Setting the time filter for the measured value. With the help of the digital filter a stable
and accurate reading can be obtained while the filter level can be set to a desired value.
The higher the filter level, the longer the response time on a value change will be.
