That document relates to maintenance testing transponders and is still valid. The transponder is told it is at various altitudes and the tech checks to see if the reported altitude matches. If proper procedures are not followed this can generate TAs and RAs but this is expected behaviour.
Leaving your transponder on on the ground can be a nuisance for ATC but it will not generate TAs and RAs to current TCAS/ACAS systems. Older systems did not filter out ground traffic and will indeed generate advisories but the solution is to upgrade the software in the system.
If your transponder does not have an auto function, don't turn it on until entering the runway for takeoff, and turn it off as soon as you exit the runway. Mode S with auto can be left in auto from startup to shutdown.
