once for normal status, if it does not blink or blinks only once in a long time, it indicates that there
is a communication fault.
Units: Indicates the system distance measurement units.
Current value: Indicates the theoretical 4-20mA current output value corresponding to the
analogue quantity to be measured, which is obtained by converting the system according to the
[high and low adjustment points] and 4-20mA [current output function], see sub-section 6.5.4.
(6-8) for the specific conversion relationship.
Fault codes: Please see Fault Analysis and Troubleshooting for specific meanings.

Return strength: The number indicates the maximum return strength within the range. With
a good metal reflector, the return strength should be around 90dB, if the return strength is less
than 30dB, it indicates a weak return signal and requires the technician to carry out the
corresponding troubleshooting.
Real time value: The real time and damping values of the echo interface are not affected by
the [Sensor type] setting and always give distance information, pointing to the selected echo
wave crest.
Echo strength unit: indicates the signal strength of the echo currently selected by the
algorithm. Due to the noise floor rising near the end of the FMCW itself, the echo strength and
echo strength units are not necessarily the same.
