CONFigure:
Definition
The CONFigure command offers a little more flexibility than the MEASure? command. The
multimeter sets the parameters for the requested function, range and resolution, but does not
make the measurements. You have an option to change the configuration. To initiate the
measurement, use the INITiate or READ? command.

Query the selected function.
READ?
The READ? command changes the state of the trigger system from "idle" to "wait-for-trigger."
When the specified trigger condition requirements are met after the multimeter receives the
READ? command, the measurement will be initiated. The results are sent to the output buffer right
away. You must enter the reading data into your bus controller or the multimeter will stop making
measurements when the output buffer fills. Readings are not stored in the multimeter's internal
memory when using the READ? command.
Using the READ? command has a similar effect as using the INITiate command followed
immediately by the FETCh? command, except readings are not buffered internally.
INITiate and FETCh?
Definition
These two commands provide the lowest level of control of measurement triggering and reading
retrieval, but offer the most flexibility. After you have configured the multimeter, use INITiate to
change the state of the triggering system from the "idle" to "wait-for-trigger." The multimeter will
start the measurements when the specified trigger condition requirements are met (after it receives
the INITiate command). The results are sent to the internal memory and stored until you are ready
to read them.
