Instructions for operation

The following rules are applicable for the operation of the pressure transmitter:
● The device counts numerical values always in an ascending order step by step starting
from the least significant digit displayed.
If you keep the button pressed for a longer time, it counts the next higher digit displayed.
This procedure is used for fast coarse adjustment over a wide number range. Release
the [↑] or [↓] button again for fine adjustment. Press the button again.
Violations of the measured value limits are output on the display by
● The keyboard must have been unlocked in order to operate the device using the
keyboard.
● If you are operating the transmitter locally, write access is denied through HART during
this time.
However, it is always possible to read the data, e.g. measured values.
Note
The setting is saved and the measured values are automatically displayed again if more
than two minutes have passed after a button was pressed for the last time.
The operating instructions in the "Local operation without display" section apply if the
device has been delivered with a blind cover.
