be multiple:
• No valid surface echo peak in
the measuring range.
• Incorrect device configuration.
The device has detected a configu-
ration error. Reasons may be multi-
ple (see Table 7-2
Description
The volume cannot be calculated correctly
with the current configuration.
The Scaled Variable configuration is incor-
rect.
The configured tank geometry results in a
too large level measuring range for this de-
vice.
Recommended actions
1. Analyze the Echo Curve at time
of loss for reason and check de-
vice configuration, especially
thresholds.
2. Check device physical installa-
tion (for instance antenna con-
tamination).
3. Consider increasing Measure-
ment Recovery Time parameter
for intermittent conditions.
4. Restart the device.
5. Restore default settings and re-
configure the device.
6. If the condition persists, replace
the device.

more information.
for details). 2. Correct the parameter causing
the error.
Recommended actions
1. If strapping table is used, check that
level-volume values are entered in in-
creasing order.
2. If strapping table is used, check that
number of strapping points to use is
correct.
3. If tank dimensions are used for volume,
check that geometry shape and size
measures are correct.
4. If condition persists, restore default
settings and reconfigure the device.
1. Check that the value pairs in the scaled
variable table are entered in increasing
order.
2. Check the number of table points to
use is correct.
3. If condition persists, restore default
settings, and reconfigure the device.
1. Check tank geometry configuration
and reduce Reference Height.
2. If condition persists, restore default
settings and reconfigure the device.
