Teaching in static interference signals
Static interference signals in the tank generated by tubes, beams, couplings,
or a cleaning ball can be taught-in. The probe length provides the value for the
teach-in depth.
1.
Log in to expert mode; see
.
2. Access the EXPRT-Pulse-CalRng menu using the arrow and Set pushbuttons.
3. Set the value range between 95 and 6005 mm.
Note:
• The value starts from the LFP process connection.
• The value should cover all interference signals.
•
Maximum value = probe length – 100 mm.
• The AutCal must then be carried out, see
• The CalRng parameter should always correspond to the probe length for LFPs with
remote amplifier.

Evaluating signal quality
Parameters describe the quality of the measuring signal.

SigQa1
Characteristic for the robustness of the EXPRT-Pulse-TrsHld setting.
Not active in foam mode. The displayed value is only valid if the sensor displays the
correct level value.
•
Value range: 0% ... 100%
•
Good signal: > 40% (a high pulse reserve is provided with the current
TrsHld setting.)
b
Measures: Reduce EXPRT-Pulse-TrsHld to increase SigQa1.
Note:
• Changing TrsHld will have an impact on SigQa2 and SigQa3.
• If a satisfactory SigQa1 value cannot be achieved by adjusting TrsHld in conjunction
with the SigQa values, the installation condition must be checked. Using a coaxial
tube improves signal detection, particularly in media with low DK values (e.g. oil).
