A-2
AS
“Big Step” Constant
Param 1: A big step value for flow measurements. Changes exceeding this
value will not be smoothed.
Param 2: A big step value for velocity measurements. Changes exceeding
this value will not be smoothed.
Param 3: A big step value for depth measurements. Changes exceeding
this value will not be smoothed.
AT
TCF
Param 1, 2, and 3 (range 0 – 1000): A time constant factor (TCF) for
smoothing flow measurements. The value entered for each parameter is
divided by 1000 to obtain the smoothing constant (e.g. entering 500 yields a
constant of 0.50).
AZ
Zero screen constant
Param 1: A zero screen value for flow measurements (in cubic cm/s). Mea-
sured values below this value will be forced to zero in the smoothed flow
data type.
Param 2: A zero screen value for velocity measurements (in cubic mm/s).
Measured values below this value will be forced to zero in the smoothed
velocity data type.
Param 3: A zero screen value for depth measurements (in mm). Measured
values below this value will be forced to zero in the smoothed depth data
type.
IP
Sets the device IP Address
Param 1 (Range 0 – 255): First byte of the address.
Param 2 (Range 0 – 255): Second byte of the address.
Param 3 (Range 0 – 255): Third byte of the address.
Param 4 (Range 0 – 255): Fourth byte of the address.
Example —
?> IP 192.168.1.10
IS
Sets the device IP subnet mask
Param 1 (Range 0 – 255): First byte of the subnet mask.
Param 2 (Range 0 – 255): Second byte of the subnet mask.
Param 3 (Range 0 – 255): Third byte of the subnet mask.
Param 4 (Range 0 – 255): Fourth byte of the subnet mask.
Example —
?> IS 255.255.255.0
LB
LCD Backlight
Param 1 (Range 0 – 1): Sets the LCD screen backlight. 0 is off and 1 is on.
LC
LCD cycle interval
Param 1 (Range 0 – 15): Sets the time (in seconds) for which each display
on the LCD is shown. The LCD loops through all screens continuously
showing each screen for the time entered here. The LCD screens can be
configured using the LD command.
LS
Display Smoothed Values
Param 1 (range 0 – 1): If 1, smoothed data types will be displayed in the
LCD and on the main webpage. If <1, measured data is displayed.
