6.5.4 Noise or weak surface echoes
In order to increase the measurement performance in difficult applications where the surface
echo peak is low compared to the noise, it is recommended to set the Performance Mode to
High (Short battery life). A low surface peak compared to the noise might be caused by a
turbulent surface, low dielectric constant, plastic tanks and so on.
If the Performance Mode is set to High (Short battery life), each update is based on an increased
number of measurements (radar sweeps), which gives improved robustness and decreases the
noise in the output value. However, the battery life is significantly reduced (between 40-60%).
To set the Performance Mode to High (Short battery life), do the following:
1. From the Home Screen, go to Service Tools > Echo Tuning > Advanced.
2. Under Performance Mode, select High (Short battery life) and then click Send.
