10.5.3 Output Commands
The following Index Velocity and Discharge Commands are used to set pa-
rameters used to control the output of the computed, flow, area, etc.
IF - Flag Counter
Purpose Sets how long to use the last good velocity and vertical range
data for discharge calculation when invalid data is measured.
Format IFn
Range n = 1 to 100
Default IF10
Recommended Setting. The default setting for this command is
recommended for most applications.
Description The Channel Master calculates cumulative volume by calcu-
lating a volume for each ensemble and adding it to the total. If
a momentary problem causes a few ensembles to have invalid
data, the volume is calculated from the last good data. The IF
command sets the number of ensembles to hold the last good
data. If the problem persists longer than this, the cumulative
volume and other discharge values are not calculated or up-
dated until more valid data is measured.
IO - Q Calculation
Purpose The IO commands enables and disables flow computation.
Format IO n
Range n = 0 (off), 1 (on)
Default IO 1
Recommended Setting. Set using WinHADCP.
Description The IO commands enables/disables computation and output of
flow, area, volume, and stage.
IU - Output Units
Purpose Selects the output units to be used.
Format IU Velocity, Discharge, Volume, Area, Stage
Range See description
Default IU 1, 1, 1, 1, 1
Recommended Setting. Set using WinHADCP.
