Transducer 1 Parameters
P020 Set DATEM 1
P020 can be accessed via the Operator Password (Default 1997).
Option
Description
0 = Quit
Leave P020 without any change to the present
DATEM trace.
1 = Capture
DATEM trace of entire visible range taken and
all echo returns referenced out.
2 = Default
DATEM trace will assume default value.
3 = Def Reset
Default DATEM to factory settings.
4 = Set Min DATEM
When set, DATEM levels at this point will be
accepted as a minimum.
This parameter allows DATEM to be reset to its default value or alternatively
allows the user to “Capture” a DATEM trace. It should be noted that when using
option 1 = Capture, all echoes seen will be eliminated by DATEM.
Option 1 = Capture
The Capture function is particularly useful when setting up applications where the
target goes out of range and the echo is lost. For example chemical or product
tanks where the bottoms are conical or parabolic and the transducer is not
centrally located on the top of the tank.
When the tank is empty a Capture can be done, by performing a Capture all
unwanted echoes from noise or obstructions will be referenced out and this will
leave the true echo visible, when it comes back into range.
Default = 0
