Peak values
When using sensors working acc. to the non-contact

ced by the respective process conditions. In this menu
item, the reliability of the level echo is displayed in dB.
The reliability is signal strength minus noise. The higher
the value, the more reliable the measurement.
Indication "OK" or flashing error message, e.g. "E013".
In addition, the error appears in clear text in the
measured value display.
