Water-Profiling Commands
The following commands define the water-track (WT) criteria used to col-
lect the water current velocity data throughout the water column.

Sets the minimum threshold of water-track data that must
meet the correlation criteria.
WCnnn
nnn = 1 to 255%
WC080
The ADFM uses WC to screen water-track data for the mini-
mum acceptable correlation requirements. The nominal
(maximum) correlation depends on system frequency and
depth cell size (WS). WC sets the threshold of the correlation
below, which the ADFM flags the data as bad and does not
average the data into the ensemble.
Selects the data types collected by the ADFM.
WDnnn n00 000
Firmware switches (see example)
WD uses firmware switches to tell the ADFM the types of
data to collect. The ADFM always collects header data,
fixed/variable leader data, and checksum data.
WD1xx xxx xxx = collect velocity data
WDx1x xxx xxx = collect correlation magnitude data
WDxx1 xxx xxx = collect echo intensity data
WDxxx 1xx xxx = collect percent good data
Sets the maximum error velocity for good water-current data.
WEnnnn
nnnn = 0 to 5000 mm/s
WE9999
The WE-command sets a threshold value used to flag water-
current data as good or bad. If the ADFM's error velocity
value exceeds this threshold, it flags data as bad for a given
