:DATA command
:DATA?
[:SENSe[1]]:DATA? Return reading.
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 refer
-
ence 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 read-
ing will be displayed on the CRT as follows: +1.000000E+01
Notice that 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.
