Appendix C: Troubleshooting
Measurement Difficulties
If the Failsafe Timer (P070) expires due to a measurement difficulty, LOE flashes
alternately with the last known Reading. In rare cases, the HydroRanger 200 may lock on
to a false echo and report a fixed or wrong reading.
Flashing LOE Display
The loss of echo (LOE) display appears when the echo confidence is below the threshold
value set in P805 Echo Confidence.
LOE occurs when:
• The echo is lost and no echo is shown above the ambient noise. See low echo
confidence (P805) and low echo strength (P806).
• Two echoes are too similar to differentiate. See low echo confidence (P805) and low
echo strength (P806).
If LOE is displayed, check the following:
• Surface monitored is within the transducer maximum range
• Transducer model (P004) matches the transducer used
• Transducer is located and aimed properly
• Transducer is not submerged without a submergence shield
Adjust Transducer Aiming
See the Transducer manual for range, mounting, and aiming details. For optimum
performance, adjust transducer aiming to provide the best Echo Confidence (P805) and
Echo Strength (P806) for all material levels within the measurement range.
The most efficient method of checking echoes is with Siemens Milltronics Dolphin Plus
software.
Displaying Echoes
Use Dolphin Plus to graphically
display the echo profile at the
installation. Interpret the echo profile
and change relevant parameters.
Editing Parameters
Edit the parameter values. Use
