Appendix C: Troubleshooting
If multiple echoes appear on the Echo Profile, typical of a flat material profile (especially if
the vessel top is domed), use the “first” Algorithm.
If the Echo Profile repeatedly switches from short to long, adjust the Short Shot Range
(P852) to stabilize the “shot” mode used for the echo evaluation. Also, adjust the Short
Shot Bias to increase (or decrease the amount of preference given to short shot echoes
over long shot echoes.
Should a stable measurement still not be attainable, contact Siemens Milltronics or your
local distributor.
Transducer Ringing
If the transducer is mounted too tightly, or if it is mounted so that its side touches
something, its resonance characteristics change and this can cause problems.
