Changing the program parameters
This section explains the exact procedure for programming in all the menus.
The order in which the menus are dealt with here is the same order in which
they appear in the display in programming mode after you have entered your
password.
5.2.1
Programming the analogue outputs
The two analogue outputs allow you to connect recording instruments,
controllers or other units. You can assign any of the measurement variables
to the outputs.
0

Don’t make any changes, go to analogue output 2
1
Change the programming of analogue output 1
You can assign any of the measurement variables to the analogue output.
ENTER
Don’t make any changes
Select measurement variable: press measurement variable key,
ENTER
You can select the output current for the output from two current ranges.
ENTER
Don’t make any changes
Select output current:
1
Output current: 0...20 mA
0
Output current: 4...20 mA
Within the overall measurement range you can define a range that is to be
split.
Example The dew-point temperature has an overall measurement range of
0...100 °C. You set the lower measurement range limit to 60°C and
the upper measurement range limit to 80 °C.
If the output current is set to 4...20 mA,
60 °C corresponds to 4 mA and 80 °C corresponds to 20 mA.
ENTER
Don’t make any changes
Select lower measurement range limit: enter new value using keyboard,
ENTER
(-50...2000)
ENTER
Don’t make any changes
Select upper measurement range limit: enter new value using keyboard,
ENTER
(RANGEST...2000)
