Service and troubleshooting tools

7.4.1

Use the echo curve

The Rosemount Radar Master Plus software includes functions for viewing and recording single instances
or movies of the echo curve. The echo curve represents the tank, as seen by the radar transmitter. Each
peak corresponds to a strong reflection of the radar signal.
When connected to Rosemount Radar Master Plus, past measurement records and echo curves including
the 10 highest peaks, as well as the 50 last alert events are automatically transferred from the
transmitter's internal memory to the hard drive on your local computer. Past measurement records are
then available the next time you connect to the transmitter using the level trend timeline (see
Figure
Measurement problems can be understood by studying the position and amplitude of the different
peaks. Additionally, the recorded echo curves give insight into unexpected and intermittent
measurement behaviors, for instance, at the time of the triggered alert.
Read the echo curve
To read the echo curve in Rosemount Radar Master Plus:
1. Under Service Tools, select Echo Curve. Rosemount Radar Master Plus reads one echo curve and then
stops.
2. To continuously update the echo curve, select the Play icon.
