4.2 Step 2 — Do a False Echo Learn Command

The 25616, Adjustment/Display Module, or the terminal emulator

in LoggerNet or PC400 can be used to enter SDI-12 commands.

Appendix B.2, Using Terminal Emulator and a Datalogger to

Send Commands, describes entering commands using the

terminal emulator.

NOTE

Do a Start False Echo Learn command followed by a Send Data command

(see TABLE 4-4). To start false echo learn, do the aXSFEL+nnn.nnn!

command (where nnn.nnn = the actual distance to the water) followed by the

aD0! (Send Data) command. TABLE 4-5 shows an example of the command

and response.

Any echo occurring 0.5 m (1.6 ft) short of the distance you entered will be

considered noise.

Appendix B describes this command in further detail.
