If a device does not have a display, its operations are limited. This is however not applicable

for selecting functions using HART.

Basic safety instructions

Note

Incorrect reproduction of the process pressure

If you have changed the basic functions of the pressure transmitter, the display and the

measurement output could be set such that the actual process pressure is not reproduced.

Therefore, check the basic parameters before commissioning.

6.3 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

or .

● 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.
