Principle of programming
For programming, you must always proceed as follows:
First change over to the display value to be modified.
To do this, press either the control button (only forwards)
or the internal buttons “+” and “-” or the external buttons “
” and “
” (forwards and
backwards).
Change to programming mode by pressing “P” for at least 2 seconds. On the left side of the
display, a flashing character or cursor will appear:
0 1 2 3.2 3 P/m3
You can now modify the flashing decimal by pressing either “+” or “
” (+1) or “-” or “
” (-1).
Example: If you press the “
“ button three times, the first decimal will be increased from 0 to 3.
If an “L” appears on the far left side of the display, this value is a list. With a list, you can only
scroll in the specified values.
After you have completed your programming of the first decimal, press “
” once and the next
character will start to flash.
Now proceed with your programming until you have reached the last decimal place.
Then press “
” once again to have the set value accepted and quit programming mode.
Press the “P“ button to set the decimal point behind the flashing digit.
With totalizers, modes and integers, no decimal point is permitted.
Press the control button if you have made an error or if you want to discontinue inputting data.
Display values
Measured values, such as the flow rate, frequency, etc. are display values and cannot be directly
modified. However, there are many parameters which influence the formation of these measured
values. These parameters are described in the following section.
Display values include the flow rate, version number, year of construction, serial number, value of
the current output in mA, for example.
