PGA sensitivity
- This parameter limits the maximum gain (amplification level) of the internal
programable gain amplifier. It is strongly recommended to use the default value 8, which allows
the internal signal amplifier to use the maximum gain when the reflected radar signal is very low.
Setting this value to a lower value is used only when the instrument is mounted very close to the
water surface, typically less than 1 metre, and in that case this parameter should be set to a value
of 4 or 5.
#set_sensitivity=<0-8>
Velocity min.
- This parameter is used for setting up the minimum velocity value of interest.
#set_max_velocity=<value>
Velocity max.
- This parameter is used for setting up the maximum velocity value of interest.

Level active zone min.

instrument will detect water level only within the range set by the

structures and objects that are present on the monitoring site, that could cause false instrument
readings. It is strongly recommended to set the

value to the maximum possible
distance between the water and the instrument at the specific monitoring site. Typically, this is the
distance between the instrument and the lowest point in the channel.

Level sensor height
- The height of the instrument needs to be set above the water zero-level
“gauge zero”. The instrument will output relative measurements of the actual water level based
on its height above the water zero-level. Example: if the instrument is mounted exactly 5 metres
above the gauge zero level, then this parameter should be set to 5 metres. Then, if the instrument
measures that the distance between the instrument and the water is 4 metres, it will report that
the water level is 1 metre, because the water is 1 metre above the gauge-zero level. For user
convenience, this parameter can also be indirectly set by inputting the current staff gauge reading.
