OPTISOUND 3010 C • Four-wire 4 … 20 mA/HART
30504-EN-220310
A background lighting integrated by default can be adjusted via the
adjustment menu. The function depends on the height of the supply
voltage. See "
Technical data/Voltage supply
".
To maintain the function of the device, the lighting is temporarily
switched off if the power supply is insufficient.
Backlight
In the default setting, the lightning is switched off.
The respective min. and max. measured values are saved in the sen-
sor. The values are displayed in the menu item "
Peak values
".

Min. and max. distance in m(d)
•
Min. and max. temperature
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 a dB
value. Measurement reliability equals signal strength minus noise. The
higher the value, the more reliable the measurement. A well function-
ing measurement normally has a value > 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.
Measurement reliability
Device status
With ultrasonic sensors, the "
Echo curve
" represents the signal
strength of the echoes over the measuring range. The unit of signal
strength is "dB". The signal strength enables the jusgement of the
quality of the measurement.
The "
False echo curve
" displays the saved false echoes (see menu
"
Service
") of the empty vessel as signal strength in "dB" over the
measuring range.
