DATEM Parameters
The following two parameters are used to make changes to the DATEM trace
such as setting it to its default value or using it to select a particular echo,
both parameters are accessed directly by simply entering
Program Mode
then typing in the parameter number and pressing ENTER .
P020 Set DATEM 1
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 DESCRIPTION
0 = Quit
Exit 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 its 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.
P021 Set Distance
Allows the user or service personnel to determine which echo is to be
displayed. On start-up, if the unit displays an incorrect reading then simply
enter the distance from the transducer to the required level and, if an echo is
present at this point, the Gate will establish itself around the chosen echo,
DATEM will update in front of the Gate and reference out any other
unwanted echoes.
It should be noted that DATEM will reset to default values whilst performing
this function, and reform itself once it has selected an echo.
Important Notice
Enter the distance measurement from the face of transducer to the target, in
units of measurement (P104) and press ENTER.
