Information on operation

The following rules apply to operation of the pressure transmitter:
● The device always increments numerical values in steps from the displayed digit of least
significance.
If you press the button longer, it increments the next displayed digit of higher significance.
This procedure can be used for fast coarse setting over a wide numerical range. For the
fine adjustment, release the [↑] or [↓] button again. Then press the button again.
Violations of the measured value limits are output on the display by
● If you wish to operate the device using the buttons, the lock must be canceled.
● If you are operating the pressure transmitter locally, write operations over PROFIBUS are
rejected during this time.
It is possible to read data at any time, e.g. measured values.
Note
If you allow more than 2 minutes to pass following the pressing of a button, the setting is
saved and the measured-value display is returned to automatically.
The operating instructions in the section "Local operation (Page 76)" apply if the device has
been delivered with a dummy cover.
