Purpose Load the SpeedOfSound variable with a single real scan from the SVSS.

Description This command loads the SpeedOfSound variable with a measured value from the SVSS, in
a manner similar to the manner the variable is loaded during deployment. The EZ com-
mand must be issued prior to this command or the function will be bypassed. Set the EZ
command to EZ3xxxxxx. The three enables communication with the SVSS. Upon success-
ful completion of the function call, the SpeedOfSound variable will contain the new value.
