Measurement old This is a temporary error message. If the
device cannot get a measurement in this
time limit, the displayed measurement
is no longer correct. The voltage is
possibly too low. If the device continues
to show the message "Spectrum quality
bad", then this message is also shown.
Do a check of the voltage at the device terminals. Refer
also to the error message "Spectrum quality bad".

Information
Peak lost in tank
bottom
Peak lost in
blocking distance
The level is in the blocking distance.
There is a risk that the product will
overflow and/or cover the device.
Remove some of the product until the level is below the
blocking distance.
Device reset The device detected an internal error
(watchdog timer issue).
Record the data that is in menu item 2.2.2 DIAGNOSTIC
(Configuration mode / Supervisor menu). Speak to the
supplier.
Current Output
Drift
The current output is not calibrated. Speak to the supplier to get the calibration procedure.
Hardware error. Replace the device.
Temperature out
of range
The ambient temperature is outside the
given range. This can cause loss or
corruption of data.
Measure the ambient temperature. De-energize the
device until the ambient temperature is back in the
given range. If the temperature does not stay in the
correct range, make sure that there is insulation
around the signal converter. If this error occurs 2
times, replace the device.
Converter memory
failure
The device's hardware is defective. Replace the signal converter.
Converter Voltage
failure
The device's hardware is defective. Replace the signal converter.
Internal
Communication
The device's hardware or software is
defective. The converter cannot transmit
signals to or receive signals from the
antenna electronics.
De-energize the device. Make sure that the signal
cable engages in the terminal and the screw
connection is tight. Energize the device. If the problem
continues, replace the signal converter.
Overfill The level is in the blocking distance.
There is a risk that the product will
overflow and/or cover the antenna.
Use a different procedure to measure the level in the
tank. Remove some of the product until the level is
below the blocking distance.
If a viscous product touched the antenna:
• remove the device and clean the antenna, or
• If the device has a purging option, use the purging
system to clean the antenna.
Peak Lost (Level
Lost)
The signal peak is not found within the
measuring window that filters the
signals received by the antenna. The
measurement is not correct. The device
will automatically increase this window
to find the correct signal.
Do a check of the device, tank and the process.
Reconfigure the device and record a new empty
spectrum. Follow the instructions on page . If
necessary, speak to the supplier.
Sensor no Signal The device's hardware is defective. Replace the signal converter.
