:DATA command

:DATA?
[:SENSe[1]]:DATA?
Description
This query command is used to read the latest instrument reading. This com-
mand 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 calcula-
tions).
The reading is returned in exponent form. For example, a 10V DC reading
will be displayed on the CRT as follows: +1.000000E+01
Notice that the measurement function is not included in the response mes-
sage. Thus, you may want to perform a function query (see previous com-
mand) after a reading query.
Return reading.
