•
"Y-Zoom": 1, 2, 5 and 10x signal magnification in "dB"

The following circumstances cause interfering reflections and can
influence the measurement:
•
High sockets
•
Vessel installations such as struts
•
Agitators
•
Buildup or welded joints on vessel walls
Note:
A false signal suppression detects, marks and saves these false sig-
nals so that they are no longer taken into account for level measure-
ment.
This should be done with the low level so that all potential interfering
reflections can be detected.
Proceed as follows:
1. Select the menu item "Additional settins" with [->] and confirm
with [OK]. With [->] you have to select the menu item "False
signal suppression" and confirm with [OK].
2. Confirm again with [OK].
