other systems, it is forbidden to modify
factory parameters during system operation.
The frequency of the sensor is the working
frequency of the ultrasonic probe, and the
setting range is 15-50kHz. The near blind
area is the closest distance measured by
the meter. When the instrument works and
the measurement enters the near blind
zone, the display value is 0.
The far threshold is the echo confirmation
value when far away from the near blind
area, and the near threshold is the echo
confirmation value near the near blind area.
When the instrument works, the echo
threshold value exceeds this value and is
confirmed as valid echo; otherwise, the
wave is lost. The far threshold value is set
between 0 and 255, and the near threshold
value is set between 150 and 250. This
parameter can be adjusted by professionals
according to the site conditions, or the far
threshold value can be set to 0 as the
automatic threshold value of the instrument.
The near threshold value must be set.
