All of the following functions in this block are only accessible via the level
2 code.
When the configuration functions have been selected in the main menu,
pressing the fifth soft key ("...more") takes you to more configuration
functions.
With the aid of this function you can determine the lower value of the
measuring range 0 - 20 mA/ 2 - 20 mA/ 4 - 20 mA/ NAMUR = 4 - 20 mA
with limit at 3.8 mA. See also the table below.
The desired value is selected by pressing the soft key assigned to it and
simultaneously the two other values are reset.
In addition, the analog output can be negated; for example, 0 ... 100 ppm
THC ≡ 0 ... 20 mA or 0 ... 100 ppm THC ≡ 20 ... 0 mA.
Note
The second analog output is not used.
Negative measured values: Should negative measured values prove to be
unsuitable for further processing, by activating this function you can limit
the negative measured values at the analog output to 0 (or 2/ 4/ 3.8
(NAMUR)) mA. The display continues to show the correct measured
value.
