:TRACe|:DATA

The bar (|) indicates that :TRACe or :DATA can be used as the root command for this subsystem.
From this point on, the documentation in this manual uses :TRACe. If you prefer to use :DATA,
simply replace all the :TRACe command words with :DATA.

:CLEar

This command is used to clear the buffer.
Usage
:TRACEe:CLEar
Details
This action command is used to clear the buffer of readings. If you do not clear the buffer, a
subsequent store overwrites the old readings. If the subsequent store is aborted before the buffer
becomes full, you could end up with some old readings still in the buffer.
