WS – Cell Size
Purpose Selects the volume of water for one measurement cell.
Format WSnnnn
Range nnnn = 100 to 1000 cm (300kHz), 100 to 800 cm (600kHz),
10 to 400 cm (1200kHz)
Default WS0100 (1200kHz), WS0200 (600kHz), WS0xxx (300kHz)
Recommended Setting. Set using WinHADCP.
Description The Channel Master collects data over a variable number of
cells. WS sets the size of each cell in centimeters.
WV – Ambiguity Velocity
Purpose Sets the radial ambiguity velocity.
Format WVnnn
Range nnn = 000 to 999 cm/s
Default WV390
Recommended Setting. It is strongly recommended that the WV
command be left at its’ default value of 390.
Description Set WV as low as possible to attain maximum performance,
but not too low or ambiguity errors will occur. RDI recom-
mends that the WV command not be set below 100cm/s. Rule
of thumb: Set WV to the maximum horizontal velocity rela-
tive to the Channel Master.
The WV command (ambiguity velocity setting) sets the
maximum velocity that can be measured along the beam when
operating in water mode 1 (WM1). WV is used to improve
the single-ping standard deviation. The lower the value of
WV, the lower the single-ping standard deviation.
