User manual

Use the DCL command to clear the GPIB interface and return it to a known state. Note
that the DCL command is not an addressed command, so all instruments equipped to im-
plement DCL will do so simultaneously.
When the Model 2000 multimeter receives a DCL command, it clears the Input Buffer and
Output Queue, cancels deferred commands, and clears any command that prevents the
processing of any other device command. A DCL does not affect instrument settings and
stored data.

The SDC command is an addressed command that performs essentially the same func-
tion as the DCL command. However, since each device must be individually addressed, the
SDC command provides a method to clear only selected instruments instead of clearing all
instruments simultaneously, as is the case with DCL.
