Min. and max. measured values are saved in the sensor. The
values are displayed in the menu item "Peak values".
l Min. and max. distance in m(d): Radar, guided microwave,
ultrasonic sensors
l Min. and max. pressure: pressure transmitter

l Min. and max. temperature: ultrasonic sensors, pressure
transmitters
Pointer
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.
In this menu item, the device status is displayed. If the sensor
detects a fault, "OK" will be displayed. If a fault is detected, a
flashing failure message is outputted sensor-specifically, e.g.
"E013". The fault is also displayed in clear text, e.g. "No
measurement value".
Information:
The fault message as well as the clear text indication are also
carried out in the measured value display.
Meas. reliability
Sensor status
With ultrasonic and radar sensors as well as sensors with
guided microwave, the "Echo curve" represents the signal
strength of the echoes over the measuring range. The units of
the signal strength are "dB" (ultrasonic and radar) and "Volt"
(guided microwave). The signal strength enables the assess-
ment of the quality of the measurement.
