Installation and Configuration
Also, or alternatively, activate the transmitter’s loop test function. Output 4, 12, and 20 mA and
verify that the readings in the DCS match up.
In Rosemount Radar Master, select Setup > Output > Analog Out 1 and click Loop test.

2.4.3 Review echo curve
1. Download and review the echo curve
2. Verify that the reference pulse is detected
3. Review peak amplitudes
For an empty vessel, verify the probe end pulse is visible. If the probe is grounded
(the end of the probe is touching a metal surface) or SST centering disk is used,
the pulse is positive. Otherwise the pulse will be negative.
Verify that no disturbing echoes are present above the Surface Threshold (ATC).
Note
Figure 2-8 illustrates the key elements of a theoretical echo curve. In an actual echo curve, the
probe end pulse and the probe end echo threshold line are not visible in an interface application,
they are shown for illustration purposes only.
