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.

TRACe:FREE?
This command is used to read the status of storage memory. After sending this

commas are sent to the computer. The first value indicates how many bytes of
memory have been stored, and the second value indicates how many bytes of
the memory can be stored.

Returns
<NR1>, <NR1>
