TRACe Subsystem Commands

Chapter8 TRACe Subsystem Commands

The commands in this subsystem are used to configure and control data

storage into the buffer.

Note:

These TRACe Subsystem Commands are only used for the single-phase

models (IT7321/IT7322/IT7322H/IT7324/IT7324H/IT7326/IT7326H), and the

three-phase models

(IT7322T/IT7322HT/IT7324T/IT7324HT/IT7326T/IT7326HT) do not apply these

commands.

TRACe:CLEar

This action command is used to clear the buffer of readings. If you do not clear

the buffer, a subsequent store will overwrite 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.

memory have been stored, and the second value indicates how many bytes of

the memory can be stored.
