FETCh? command

:FETCh?
Description
This command configures the instrument for subsequent measurements on
the specified function. This command places the instrument in a "one-shot"
measurement mode. You can then use the :READ? command to trigger a
measurement and acquire a reading (see :READ?).
When this command is sent, the Model 2010 will be configured as follows:
• The function specified by this command is selected.
• All controls related to the selected function are defaulted to the *RST
values.
• Continuous initiation is disabled (:INITiate:CONTinuous OFF).
• The control source of the Trigger Model is set to Immediate.
• The count values of the Trigger Model are set to one.
• The delay of the Trigger Model is set to zero.
• The Model 2010 is placed in the idle state.
• All math calculations are disabled.
• Buffer operation is disabled. A storage operation presently in process will
be aborted.
• Autozero is set to the *RST default value.
• All operations associated with switching cards (scanning) are disabled.
This command is automatically asserted when the :MEASure? command is
sent.
PRINT #1, "output 16; :conf:volt:dc"
This command requests the latest post-processed reading. After sending this
command and addressing the Model 2010 to talk, the reading is sent to the
computer. This command does not affect the instrument setup.
This command does not trigger a measurement. The command simply
requests the last available reading. Note that this command can repeatedly
return the same reading. Until there is a new reading, this command
continues to return the old reading. If your application requires a "fresh"
reading, use the :DATA:FRESh? command (see the SENSe Subsystem
command).
This command is automatically asserted when the :READ? or :MEASure?
command is sent.
