In the menu item "Sensor-TAG" you edit a 12-digit measurement loop
name. An unambiguous designation can hence be assigned to the
sensor, e.g. the measurement loop name or the tank or product des-
ignation. In digital systems and in the documentation of larger plants,
a singular designation should be entered for exact identification of
individual measuring sites.
The available digits comprise:
•
Letters from A ... Z
•
Numbers from 0 ... 9
•
Special characters +, -, /, -
Factory setting is "Sensor".

Peak value indicator
When non-contact level sensors are used, the measurement can be
influenced by the respective process conditions. In this menu item,
the measurement reliability of the level echo is displayed as dB value.
The measurement reliability equals signal strength minus noise. The
higher the value, the more reliable the measurement. With a function-
ing measurement, the values are > 10 dB.
The instrument status is displayed in this menu item. If no failure is
detected by the sensor, "OK" will be displayed. If a failure is detected,
there will be a sensor-specific flashing fault signal, for example
"E013". The failure is also displayed in clear text, for example "No
measured value available".
Information:
The fault message as well as the clear text indication are also carried
out in the measured value display.
