Xylem H-3551 - Manual (Page 30)

5-12 SDI-12 Command and Response Protocol
H-3551
5.14 Extended “XTEST” Command
This command is used for installation and testing and requires the use of a H-4191 Sidekick
interface and a PC. This command causes the H-3551 to display a listing of the H-3551's current
settings, followed by a repeating printout of real-time measurement data. This is not compliant
with the SDI-12 specification and is not used with data loggers.
An example of an “XTEST” printout is shown below:
