Solution
The displayed level value / SPx/
RPx / FHx/FLx / QALOW/QAHIGH
is greater than the probe length
An offset was configured for the
level value
Adjust offset
(See Chapter 5.10 "Setting the
offset")
Incorrect probe length configured
Adjust probe length (see Chapter
5.4 "Configuring the probe
length")
Level occasionally jumps to a
higher value
Contamination in the vicinity of
the process connection
Clean
Spray ball or feed dampen probe
with medium above the medium
surface
Observe the installation condi-
tions
Configure the MaxCoL plausibility
filter

Change in the ambient conditions
regarding the situation during the
AutCal process
Perform commissioning again
(see Chapter 2
"Commissioning the
NGR
")
Significant buildup of foam
Perform foam commissioning
(see Chapter 2.3 "Foam commis-
sioning")
TrsHld set too low, the echo
algorithm detects interference
reflections
Increase TrsHld
Level occasionally jumps to 0 mm TrsHld set too high
Perform advanced commissioning
(see Chapter 2 "Commissioning
the
NGR
")
Significant buildup of foam
Perform foam commissioning
No measurement of low levels for
media with low DKs
Increased inactive range at the
probe end for media with a low
DK
Increased measurement inaccu-
racy
Use of foam algorithm
