"Probe settings" submenu
The Probe settings submenu helps to ensure that the end of probe signal within the
envelope curve is correctly assigned by the evaluation algorithm. The assignment is correct
if the length of probe indicated by the device matches the acutal lenght of the probe. The
automatic probe length correction can only be performed if the probe is installed in the
vessel and is completely uncovered (no medium). For partially filled vessels and if the
probe length is known, select Confirm probe length (→  163) = Manual input in order
to enter the value manually.
If a mapping (interference echo suppression) has been recorded after shortening the
probe, it is no longer possible to perform an automatic probe length correction. In this
case there are two options:
• Delete the map using the Record map parameter (→  138) before performing the
automatic probe length correction. After the probe length correction, a new map
can be recorded using the Record map parameter (→  138).
• Alternative: Select Confirm probe length (→  163) = Manual input and enter
the probe length manually into the Present probe length parameter →  162.
An automatic probe length correction is only possible after the correct option has
been selected in the Probe grounded parameter (→  162).
