:DATA command

:DATA?
[:SENSe[1]]:DATA?
Description
:FRESh?
[:SENSe[1]]:DATA:FRESh?
Description
This query command is used to read the latest instrument reading. This
command returns the raw reading or a reading that is the result of the
Reference (REL from the front panel) operation. For example, if a reference
value of 1.0 is established, the reading returned by this command is the raw
reading minus 1.0. Calculated (MATH) readings cannot be read with this
command (see the CALCulate subsystem for information on how to read
math calculations).
The reading is returned in exponent form. For example, a 10V DC reading
will be displayed on the CRT as +1.000000E+01.
The measurement function is not included in the response message. Thus,
you may want to perform a function query (see previous command) after a
reading query.
This query command is used to return a new (fresh) reading. This command
will not request the same reading twice. If a new reading is triggered, this
command will wait until the reading is available, rather than request the old
reading.
Return reading.
Return new reading.
